Is it possible to have Matlab try for a network license first, then fail over to a standalone license if it can't get a network license?

Is it possible to have Matlab try for a network license first, then fail over to a standalone license if it can't get a network license?

A network license is easier to keep up to date, but I have machines that must be able to start Matlab if the network happens to be down.

I believe this can be done in the following 2 ways :

1. Using the environment variable MLM_LICENSE_FILE (or LM_LICENSE_FILE):
2. Using the "-c" startup flag for MATLAB

Using the environment variable MLM_LICENSE_FILE (or LM_LICENSE_FILE):

By setting the environment variable MLM_LICENSE_FILE (or LM_LICENSE_FILE), you can insert a new license search path for MATLAB. The variable value will be searched first, but this will not override the original search path. The value for this variable can either be a path to a license file, or it can be used in the port@host notation. For example, to have MATLAB check against the server "license1" on port 27000, you would set the variable value to be: 27000@license1.

You can also manually specify the location of the license file with the -c option to the MATLAB startup script. This can be achieved by editing the "Target" field in the MATLAB shortcut.

For example:

• Right click on the MATLAB shortcut and choose "Properties"
• In the "Target" field, add -c and the path to the license file after the end quotation mark:

 "C:\Program Files\MATLAB\R2009b\bin\matlab.exe" -c "C:\Program Files\MATLAB\R2009b\licenses\test.lic"

Using the -c flag will override any default license search paths unlike the MLM_LICENSE_FILE variable.

To find the default locations for MATLAB license files, see the related solution:
