Hi Maria,
could you please explain a little bit what you are doing. It looks like using a timer

Hi Maria,
please try to increase your java heap space from MATLAB. You can find this option under File -> Preferences -> General -> Java Heap Memory. Please make a restart of MATLAB after changing this value.

2010a and higher having this options in the Preferences. For older Mls one has to create a java.opts file. How to do this can be found here:
