10.5: Fix a slow Matlab IDE under 10.5 Apps
Fri, Dec 7 2007 at 7:30AM PST • Contributed by: Anonymous
If you've upgraded to Leopard and now find the IDE of the new Matlab release 2007b to be super-slow, create a file called java.opts in your /Applications » MATLAB_R2007b directory, and add the following line to it: 
-Dapple.awt.graphics.UseQuartz=true
Then restart Matlab. This will switch Matlab back to using the Quartz drawing enginge (as it was in previous versions of OS X). Please find the original hint for this solution in this thread on the Mathworks Matlab forums.

For those who have older versions of Matlab (I have the 7.0 R14 Student Version), you will have trouble running the IDE itself -- it doesn't launch. I run

$ matlab -nojvm

in the Terminal anyway, so I never noticed this was a problem, but running without the Java Virtual Machine has many advantages anyway, such as that it uses less system resources and reduces crashes.

(In short, to fix a slow Matlab IDE in Leopard, don't use the IDE!)

Or if you need Matlab's Java virtual machine support for whatever reason, but don't want to run the IDE:

$ matlab -nodesktop

To make this hint work under R2008a the java.opts file needs to be in

/Applications/MATLAB_R2008a/bin/maci

In Matlab R2009a the file java.opts again needs to be in /Applications/MATLAB_R2009a.app/
