Running COMSOL with MATLAB
Running COMSOL with MATLAB requires a LiveLink™ for MATLAB® license. To run COMSOL with MATLAB, double-click the COMSOL Multiphysics 5.2a with MATLAB icon on the desktop.
Alternatively, start COMSOL with MATLAB from the Start menu by pointing to Programs, then to COMSOL 5.2a, and then select COMSOL Multiphysics 5.2a with MATLAB. For Windows 8 and later, corresponding tiles and desktop icons are added, and you can click COMSOL Multiphysics 5.2a with MATLAB on the start screen to launch COMSOL.
Running COMSOL with MATLAB starts a COMSOL Multiphysics Server and a MATLAB Desktop. The COMSOL Desktop is not involved. You can change the path to the MATLAB installation in the Preferences window accessed from the Options menu of the COMSOL Desktop. For more information, see the LiveLink™ for MATLAB® documentation.
starting COMSOL with MATLAB using the graphics server
To display the plot in a COMSOL graphics window you need to run COMSOL with MATLAB using the graphics server. To do so, append the flag -graphics to the COMSOL with MATLAB target path.
