License Management (MATLAB Installation Guide for PC)

MATLAB Installation Guide for PC

Using the Command Line

All the FLEXlm license management tools are packaged into a single executable called lmutil.exe. The installer puts this program in the $MATLAB\flexlm directory.

You invoke each separate tool using the format

lmutil command

where command is the name of the individual tool.

For example, to monitor the status of network license activity, you can use the lmstat tool.

Note In this example, note the use of the -c flag to specify the location of the License File. You must specify this flag with every tool invoked through lmutil.exe.

lmutil lmstat -a -c C:\matlab6p1\flexlm\license.dat
