Release Notes For Mathcad 11 Enterprise Edition

Under regular usage, license administration places little load on your server or network. The FLEXlm license daemon and Mathsoft vendor daemon both require approximately 3 MB of memory when running. Additionally, aside from license check-out and check-in, and periodic “heartbeats” sent out to verify the continued presence of the license server, Mathcad generates no network traffic to the FLEXlm server when running. However, as more workstations access the license server, network traffic may become an issue, and your log file will grow more quickly.

Workstation Requirements

· PC with Pentium/Celeron 233 MHz. 300 MHz or higher recommended

· Windows 98 SE, ME, NT® 4.0 SP6, 2000 SP2, XP or higher

· Minimum 96 MB of RAM. 256 MB or higher recommended

· At least 150 MB of hard disk space (5 MB for workstations utilizing a Server-based Shared Installation.)

· CD-ROM or DVD drive (not required for server-based installations.)

· SVGA or higher graphics card and monitor

· Mouse or compatible pointing device

· Internet Explorer version 5.5 or higher

2. Contents of the Mathcad Installation CD

5. Additional Mathcad Help

Be sure to check out the online Developer’s Reference and the Author’s Reference. You can find them under the Help menu in Mathcad.

The Developer’s Reference is for advanced Mathcad users. It provides information on customizing components using scripting, using the Scriptable Object component, building components in C++, and using Mathcad as an Automation server. Customizable components include the Data Acquisition Control (DAC) component and the Mathsoft Controls.

The Author’s Reference contains instructions and tips for creating Mathcad E-books and information about how to create a MathML Web site.

6. Requirements for Application Components

Mathcad uses components to communicate and exchange data with the applications Axum, Excel, MATLAB, SmartSketch, and S-PLUS as well as external data sources. Components are specialized OLE objects that not only link to external data sources and applications but also allow you to compute with these sources or applications within your Mathcad worksheet.

Using the Axum, Excel, MATLAB, S-PLUS, and SmartSketch components

To use the Axum, Excel, MATLAB, S-PLUS, or SmartSketch component in Mathcad:

· You must have a supported version of the corresponding application on your system:

Component	Requires…
Axum	Axum 5 through 7
Excel	Excel 7.0 or higher
MATLAB	MATLAB Professional 4.2c through MATLAB 6
S-PLUS	S-PLUS 4.5 through 7
SmartSketch	SmartSketch LE, SmartSketch 3 or higher

· You must have sufficient memory on your system to run both Mathcad and the other application(s). In practice, we recommend a minimum of 128 megabytes of RAM.

· Worksheets that include components can be shared with other Mathcad users; however, the components will not compute unless the person receiving the worksheet has all the necessary applications installed on his or her system.

7. Troubleshooting

Backward compatibility

If you experience any new errors on calculations that worked in previous versions of Mathcad, try switching the calculation mode. Select Worksheet Options under the Tools menu. On the Calculation tab, select Backward Compatibility under Performance Preferences. This setting is a property of the document. So, will only need to do this once as long as you save the document with this setting.

Printing or display problems

If you are using Windows 98 and a PostScript printer driver, you may have display or printing problems. Operators or parentheses may not appear on the screen correctly, they may disappear, or they may not print properly. If you encounter these difficulties you may need to adjust your font settings for the Windows PostScript printer driver. Depending on your printer settings, the print driver may substitute the PostScript Symbol font for the TrueType Symbol font used by Mathcad, resulting in a variety of output problems. To correct the problems:

1. From the Start menu, select Printers. Right click on the PostScript printer driver you are using and choose Properties.

2. In the Properties dialog, click the "Fonts" tab and select "Always use TrueType fonts." Alternatively, to ensure that you do not encounter problems in other applications, use the following steps in the Properties dialog:

a. Select the first radio button for font substitution and click "Edit the Table."

b. Scroll down to Symbol and set it to "Send As Outlines"(the topmost selection in the drop-down list)

c. Click "OK."

d. On the Fonts tab, click "Send Fonts As..."

e. In the Send Fonts As dialog, check the "Favor system TrueType fonts ..." checkbox.

f. Click "OK" then click "OK" again to dismiss the Properties dialog.

Printing worksheets containing controls

You may find that controls (sliders, in particular) do not print properly in Mathcad 11. This is a known limitation.

Trace Error in solve blocks

You may find that Trace Error does not trace for undefined variables, including global variables, in solve blocks, specifically, PDE Solve Blocks. Currently, this is a known limitation of the Trace Error feature.

Matrix Multiplication now returns scalar, not a 1x1 matrix

In previous versions of Mathcad, if you multiplied two matrices and the result was a single number, such as multiplication of a row vector and its transpose, the result was a 1x1 matrix containing the scalar result. Now, Mathcad returns a scalar. This may break worksheets with definitions that took advantage of the 1x1 matrix construct.

Problems with user defined functions

UserEFI DLLs are supported for Version 6 SP4 of Visual C++ and should be recompiled in that version if problems exist.

Multiple blank icons in task bar when opening a MathML worksheet

If you open a Mathcad worksheet that was saved in HTML format with embedded MathML regions, you may see multiple blank icons appear in the task bar while the file is opening. These icons should disappear once the file has been completely opened and they do not affect the performance of the file in Mathcad.

Initialization error when creating animation

You may get an “Error initializing video stream” message when trying to create an animation in Mathcad. The following video codecs are known to cause errors:

Microsoft H.263 Video codec

Microsoft H.261 Video codec

Intel 4:2:0 Video V2.50

This is a third party problem as Mathcad does not install any video drivers or codecs. To fix the problem, try running Windows update or downloading the latest video driver.

Nudging regions taking too long

Nudging regions is more responsive with Automatic Calculation turned off especially for larger worksheets, because Mathcad may continue to calculate during a nudge operation and significantly slow down performance. To turn off Automatic Calculation, uncheck this option under Tools Þ Calculate.

Embedding Mathcad as an OLE object

If you are embedding a Mathcad document as an OLE object in a third party application, such as Microsoft Word or Excel, it is recommended to embed an existing Mathcad worksheet rather than creating a new embedded Mathcad worksheet. When a new Mathcad worksheet is created through embedding, autocalculation is turned off and there is limited functionality of Mathsoft Controls and third party components in a Mathcad worksheet.

Difficulty using the Collaboratory User Forums

If you are experiencing difficulty with the Collaboratory User Forums and are using Internet Explorer 5.0 or lower as your browser, please note that Mathcad requires IE 5.5 or higher to take advantage of the latest Internet functionality. You can install IE 6.0 from the Mathcad CD or you can update to IE 5.5 by going to the Download area of the Microsoft Web site (http://www.microsoft.com/).

Making a User DLL appear in the Insert Function dialog box

If you create a function DLL using C or C++, you can make the function appear in Mathcad’s Insert Function dialog box by adding an entry for the function to the file USER.XML located in the \DOC\FUNCDOC subfolder of the Mathcad folder. For more information on creating a function DLL and editing the XML file, refer to the Developer’s Reference, which may be accessed from the Help menu in Mathcad.

Changes to wave and iwave functions

In Mathcad 2000, the boundary wavelet coefficients for the wave and iwave functions were rotated with respect to their counterparts in Mathcad 8. This functional change was carried forward to the current version. You may therefore see different but correct results from these functions in Mathcad 11 as compared to Mathcad 8.

Illegal context error in a function definition

Definitions such as f(x):=j+x where j is a range variable are no longer supported. Definitions that use range variables on the right that do not appear as either subscripts or function arguments on the left are illegal. They issue the error "Illegal context. Press F1 for help." If you created a worksheet in an earlier version of Mathcad that contains such definitions, consider redefining your functions so that the range variable is an argument. For example, f(x):=j+x can become f(x,j):=j+x. Alternatively, select Backward Compatibility mode on the Calculation tab under Tools Þ Worksheet Options.

Keystrokes differ from previous versions

The keystrokes for common tasks can be either the Windows standard keystrokes or the ones used in Mathcad 8 and previous versions. For example, the Windows standard keystrokes are [Ctrl]P for Print (not the Greek letter p) and[Ctrl]Z for Undo (not infinity).

If you prefer to use the keystrokes used in earlier versions of Mathcad, choose Preferences from the Tools menu and remove the check next to "Use Standard Windows Shortcut Keys."

The following keystrokes change depending on whether you use Windows standards:

Action	Windows Standard	Mathcad 8 and lower
Print	Ctrl P	None
Undo	Ctrl Z	Infinity
Redo	Ctrl Y	None
Find	Ctrl F	Ctrl F5
Replace	Ctrl H	Shift F5
P	Ctrl Shift P	Ctrl P
Insert Function	Ctrl E	Ctrl F
Infinity	Ctrl Shift Z	Ctrl Z
Select All	Ctrl A	None
Math in text	Ctrl Shift A in text	Ctrl A in text
Left limit	Ctrl Shift A	Ctrl A
Insert page break	Ctrl Enter	None
Right limit	Ctrl Shift B	Ctrl B
Chemistry mode	Ctrl Shift J	Ctrl Shift O
Move regions up	Delete key	Ctrl H
Exit a text region	Ctrl Shift Enter	Shift Enter
New line in text paragraph	Shift Enter	None
Mode for typing symbols in a name	Ctrl Shift K	Ctrl Shift P

Break statements outside of a loop behave differently

The behavior of the "break" programming operator in Mathcad 11 is slightly different from the behavior in Mathcad 2000, but returns to the behavior of the operator in earlier versions. If you use the "break" programming operator in the main branch of a program or within a "for" or "while" loop, "break" returns the result of the last statement executed. In Mathcad 2000, if the "break" operator was used in conjunction with the "if" operator, it returned a 1, since the condition is true when the break is executed.

3D graphs that require more than one argument

Since Mathcad 11 supports multiple 3D plots per graph, there must be parentheses around the arguments for a single three-dimensional plot that requires more than one argument. For example, a 3D scatter plot requires three arguments separated by commas. In Mathcad 11, these arguments must be enclosed together in a set of parentheses. If you open a worksheet containing a 3D scatter plot created in Mathcad 7 or earlier, you’ll see parentheses around the arguments.

3D graphs disappearing

If 3D graphs disappear or turn black at the bottom as you scroll down in a worksheet and you have a Diamond Fire GL 1000 Pro video driver or similar, visit http://www.diamondmm.com/ on the Web and verify that you have the latest version of the driver as well as the latest version of the BIOS.

Scalar results enclosed in parentheses

A 1x1 array may occasionally be returned as a result. In Mathcad 11, such an array appears as a number enclosed in parentheses.

Infinite integrals

Mathcad requires any function being integrated over an infinite limit to be real.

Variable names and SI units

The SI unit system is the default unit system in Mathcad 11, giving you access to standard SI unit names (including single-letter abbreviations such as A for ampere, N for newton, etc.). Take care when defining variables in Mathcad worksheets not to redefine built-in unit names in the SI system. Choose Unit from the Insert menu to browse a list of units in the default unit system of your worksheet.

Obsolete functions

The functions READ, WRITE, APPEND, and until have been removed from Mathcad. If you have worksheets, written in a previous version of Mathcad, that contain any one of these functions, you will see an error message that reads "Obsolete function." Use the File Read/Write component, the READPRN, WRITEPRN, or APPENDPRN functions, or programming instead.

Accessing the Collaboratory User Forums (formerly the Collaboratory)

To access the Collaboratory User Forums in Mathcad 11, choose User Forums from the Help menu, or go directly to the Web site at http://collab.mathsoft.com/~mathcad2000.

Multiple uses for quote key

The quote (") has many uses in Mathcad 11. In a blank space in the Mathcad worksheet it begins a text region. If you have selected a math expression, it introduces the complex conjugate operator. In a math placeholder it begins a string variable.

Importing MATLAB .MAT files

If you use MATLAB 5 or 6, you must save your MATLAB data/environment (.MAT) files in version 4 format before importing them with either the File Read/Write component or the Input component. MATLAB 5 and 6 support the "-v4" switch on the save command to save a MAT file in version 4 format. See the MATLAB documentation for details.

MATLAB allows you to save a "sparse array" (an array containing rows or columns of zeros) using special sparse array notation. Mathcad does not convert the sparse array notation if you import the array with either the File Read/Write component or the Input component; they read in the array exactly as it is stored in the file.

Using the Excel component with a worksheet containing a macro

If you insert the Excel component by referencing an Excel file containing a macro, you may encounter an "OLE timeout" dialog box. To continue loading the file, click "Yes" on the dialog box.

Exporting to dBase files

When you export data from Mathcad to a dBase file, the values are truncated to four decimal places.

Unable to print

If your printer has an extremely long name, you could experience a system error when printing from Mathcad. Try shortening the name of the printer icon in the Control Panel to prevent this from happening.

Black boxes appear when printing

If you print a worksheet containing an operator such as a summation, you may see black boxes on the printout if you are printing to a PostScript printer. To correct this, use a non-PostScript printer driver that is compatible with your printer.

Text doesn't appear in Print Preview

Gray and silver text does not appear on the screen when you choose Print Preview from the File menu but it will print.

Using the .Value property of the Scriptable Object component

In Mathcad 7, it was necessary to use a structure such as Inputs(0).Value(0,0) in a script in order return a scalar. In Mathcad 2000 and 2001i, Inputs(0).Value returns either a scalar, a vector, a matrix, or a string (Mathcad 11), depending on the type of data that is in Inputs(0).

Saving worksheets as previous versions

When you save a Mathcad 11 worksheet as a worksheet from an earlier version of Mathcad, regions or features that won't work in earlier versions are saved as bitmaps. However, these bitmaps may not closely resemble the regions or features if you save the worksheet using 256 colors.

Opening Mathcad 6 worksheets in Mathcad 11

You can open any Mathcad 6 for Windows or Macintosh worksheet in Mathcad 11. In general, the worksheet will maintain its previous appearance. However, live symbolic keywords are converted into the new symbolic keyword operator in Mathcad, and file associations are translated into full pathnames. File variable arguments appear as strings inside data file functions such as READPRN and WRITEPRN.

However, be aware that Mathcad 6 files are in ASCII format. If a Mathcad 6 file has been opened in a text editor and saved again, it may not read properly or at all into Mathcad 11. If Mathcad 6 files appear to be corrupted in Mathcad 11, try opening and saving these files as Mathcad 6 worksheets in Mathcad 6.

Backtracking while browsing the Web

If you jump to a document from a framed page while browsing the Web using the Resources window, pressing the Back button brings you to the previously loaded page instead of the framed page.

Inserting a picture

In Mathcad 6, it was possible to choose Picture from the Insert menu and enter the name of a BMP file such as bird.bmp directly into the placeholder. The argument bird.bmp was not entered as a string. This kind of argument is no longer supported in Mathcad 11. If the argument is a filename, it must be typed as a string. For example, enter "bird.bmp" in the placeholder.

Difficulties creating an animation or inserting a component

You could experience system difficulties while creating an animation under Windows NT if your TEMP variable points to a folder that does not exist. Make sure the TEMP variable points to an existing, writable folder. To set this variable under NT 4.0, click on My Computer with the right mouse button, choose Properties, and click on the Environment tab.

Personal QuickSheets

If you created Personal QuickSheets using a previous version of Mathcad, save them to another directory before uninstalling your current version of Mathcad and installing Mathcad 11. You can open them in Mathcad 11 by choosing Open from the File menu, selecting the folder in which you have them saved, and typing *.MCU in the File Name. Your Personal QuickSheet is a file with the MCU extension.

Mathcad and Axum

To insert Axum graphs in Mathcad 11 worksheets:

· Install Axum 5.0c (dated 5/18/97) or later.

· Refer to Help in Mathcad for information on the Axum component. Note that information about using Axum in Mathcad in the online Help in Axum may be out of date.

· Refer to the online Help in Axum for information on required data formats for particular graphs.

Unexpected behavior

If you are experiencing unexpected behavior with Mathcad 11, such as getting error messages when you shouldn’t or seeing internal errors, the following steps may correct your problem:

· Make sure you have no other version of Mathcad except Mathcad 11 installed on your system.

· Windows XP users can go to the Windows Control Panel under Add/Remove Programs to select Mathcad 11. Click on Support Information and run Repair.

· Make sure virus checking is off before installing Mathcad. We have seen problems with both Norton and McAfee anti-virus software, as well as other products.

· Don't run Norton CrashGuard together with Mathcad since it can misinterpret normal program operations as crashes.

· Make sure you have up-to-date versions of video and other device drivers installed. Updated versions are usually available on the Web sites of your computer manufacturer or device vendor. Many users have corrected errors by simply updating their drivers.

By taking these steps, you can avoid many common problems in your use of Mathcad 11. If you encounter any errors after taking these steps, please contact Technical Support with the details and sample Mathcad files, if applicable, so that the problem can be investigated further.

Solve blocks take a long time to calculate

Mathcad 11 uses a series of algorithms to find the result to a solve block. This process can take longer to find a solution. If you want to speed up the process, right-click on the find or minerr function which closes the solve block and choose Nonlinear/Levenberg-Marquardt from the pop-up menu.

Other difficulties with solve blocks

If you experience other difficulties with solve blocks such as failures to converge to a solution, right-click on the find or minerr function which closes the solve block and choose Nonlinear/Levenberg-Marquardt from the popup menu. In particular, if you use the result from one solve block in another and are seeing the error "Can’t understand something in this expression," choose Levenberg-Marquardt for each solve block.

Error messages:

· Failed to create function manager.

· Failed to create garbage collector.

· Failed to create allocator.

· Failed to create compute engine.

· Failed to create symbolics engine.

· Failed to initialize compute engine.

· Failed to find connection point.

· Failed to establish connection.

If you see these errors when starting Mathcad, do the following:

1. Uninstall any older version of Mathcad.

2. Reinstall Mathcad 11.

Vectors have more elements

If you define j:=0..4, and then define x[j:=0,1,2,3 (a vector with j as the subscript), Mathcad creates a 5-element vector whose elements are 0, 1, 2, 3, 0. Previous versions of Mathcad created a 4-element vector containing only the elements 0, 1, 2, 3. If you used a definition like this in the past, you may now notice some vectors with more elements in them.

Evaluation of 0*expression and 0/expression

When you evaluate 0*matrix, Mathcad no longer returns the scalar value. It now returns a matrix of 0’s. Similarly, any expression of the form 0*(expression that would return an error) or 0/(expression that would return an error) will now return an error instead of 0.

The symbolic processor recognizes range variables

The symbolic processor is now able to understand a range variable definition in a worksheet. Therefore, if you define a range variable, say x, and then evaluate an expression in x symbolically, the result will be a range of values or expressions, not a single expression in x. To work around this situation, and thus simulate the behavior of previous versions of Mathcad, define x:=x above your symbolic calculation.

Errors in new definitions persist

Mathcad no longer reverts to old definitions when an error occurs. For example, if you first define x := 3, and then define x := 2 + ln(0), you will now get an error when you evaluate x. In previous versions of Mathcad, this evaluation would return x = 3, but now the error from the second definition persists.

Scripting changes in the Scriptable Object component

There are two changes:

· Subscripting the Value of Inputs or Outputs (in a construct like Inputs(0).Value) must now match the data structure you access. You do not need a subscript for a scalar value (for example, Inputs(0).Value); you need a single subscript for vector (for example, Inputs(0).Value(0)); you need a double subscript for a matrix (for example, Inputs(0).Value(0,0)). Scripts can use the IsArray, IsNumeric, etc., functions of VBScript to figure out how to access the incoming data if they are written as general-purpose script code.

· Strings are now accepted as input and returned as output. Strings use the scalar notation (no subscript) in terms of the Value member of Inputs or Outputs, because a string is a scalar value in Mathcad. A numeric conversion must be used to change it to a number in your script.

MathConnex no longer working or missing

If you upgrade to Mathcad 11 from a previous version of Mathcad that included MathConnex, you need to update to the version of MathConnex build for Mathcad 11. Go to the Download area of the Mathcad Web site (http://www.mathcad.com/) and download MathConnex.

Increasing Virtual Memory

If you are performing calculations using large data sets (i.e., large vectors\matrices, large systems of differential equations, calculations using more than 100 variable definitions in a worksheet, etc.) you may want to increase the amount of virtual memory on your system to improve calculation speed. Mathcad may perform better with at least 1 gigabyte of free hard drive space for virtual memory usage.

Improvements to ODBC Component

For users accessing data from a database Mathcad has a default timeout of 15 seconds. If you are performing complex queries on large databases this setting can be increased for queries that take longer than 15 seconds. You must edit the registry to make this change. Under HKEY_CURRENT_USER\Software\Mathsoft\Mathcad\Preferences edit the DWORD value ODBCQueryTimeout=n, where n is the number of seconds. A registry setting of –1 (or no setting at all) means leave the ODBC default alone, the default being 15 seconds.

WARNING: Editing the registry incorrectly could disable your system from booting. If you are unfamiliar with registry protocols, seek the assistance of an IT support person.
