Alternatively, assign start-up options in the MATLAB
.matlab7rc.sh Start-up File. Modifying the
.matlab7rc.sh file defines start-up options every time
you start MATLAB.
MATLAB uses the Java® Virtual Machine (JVM™) software to run the desktop and to display graphics. The
-nojvm option enables you to start MATLAB without the JVM. Using this option minimizes memory usage and improves initial
start-up speed, but restricts functionality.
