When calling a MATLAB function, I get error message of undefined function or license error. However, as ver results show, I have already installed the toolbox product and I can find the .m file in the correct matlabroot folder.

For working from home, when you are using a floating license, it might be a license issue due to sluggish network. To determine, retrieve the network license manager log file, which should be located in:

Linux:

/var/tmp/lm_TMW.log

Mac:

/var/tmp/lm_TMW.log

Windows:

$MATLABROOT\etc\lmlog.txt

Default $MATLAB\FNP_DIR\debug.log

Path specified in LMTOOLS

In the license manager log, you are likely to see error or failure. To workaround, reach out install support team ( info@mathworks.com ) with error message in the log.
