How can I speed up Matlab 6.x?
Because of the graphical interface, many users find Matlab 6 more inconvenient to use and much slower than previous versions. Here are some tricks to get back to the old nice Matlab feeling: Using the “matlab -nodesktop” command, no extra “desktop” will be created by matlab and the input will be done through the xterm as in Matlab 5. This will speed things out a little bit. If more speed is needed, “matlab -nojvm” should be used. With this flag, matlab will not start the Java Virtual Machine which takes a lot of computing power and is not used by most of the users anyways.
