In general, increasing the Java heap size should improve performance.

@Maamar – without knowing what your loop looks like it is impossible to provide a specific answer.

One memory leak that has been fixed in R2013a relates to using drawnow within a loop – maybe this is the case that you have.

I have an open loop in my file and that is by using the command for n=1:inf
I do some calculations in such calculation and I use the command clear all at the end of each loop.
Unfortunately, the program runs for 1 hour and crashes later because of the out of memory message
It seems that there there is a leak in the memory whenever we jump from one loop to the next one.

Can any body help or tell me how to clear the command function at the end of loop and that is to avoid matlab crashes later.

Thank you

@Yair – Actually, the documentation is in error. I was alarmed by what you posted that is from the documentation — the ‘Callback’ property is not listed as being governed by the ‘Interruptible’ property. I therefore contacted Mathworks to ask if the behavior of handle graphics has changed in the newer releases to exclude the ‘Callback’ property from ‘Interruptible’ consideration. Tech Support told me that the behavior has not changed, agreed that documentation was confusing, and would take action to fix it.

@Byron – thanks for sharing
