Hi,
I am running the student version of R2011a and I recently changed a setting in Preferences->General->Java Heap Memory. In this menu I changed the amount of memory that Java can use from 128 megabytes to 4 gigabytes (my computer has 16 gigs of memory so 4 gigs shouldn't be a problem). Since making this change I am getting a Fatal Error On Startup message that says "Unable to start the JVM because of an invalid Java option" whenever I start Matlab.
I am able to start Matlab from the command line without running the JVM but I haven't been able to change settings when running Matlab like that.
I have been unable to find my Matlab install disk to reinstall Matlab otherwise I would have just done that.
Is there anyway to change a configuration file to revert this change? Or does anyone know another solution to my problem?
Thanks in advance,
Ethan

Late late answer, but maybe will help others :). In Windows 7 go to C:\Users\user_name\AppData\Roaming\MathWorks\MATLAB\R2010b\matlab.prf Search for JavaMemHeapMax and change its value to something smaller. In my case looks like this: JavaMemHeapMax=I1024
