MATLAB Central Newsreader - java heap space error

java heap space error

Dave Brackett — Mon, 01 Sep 2008 06:45:03 -0400

I am running a lengthy genetic algorithm optimisation but
after some time of running I get the following error
causing the optimisation to cease, even though Matlab still
says it is busy. Anyone got any ideas of how I can avoid
this? Thanks.

Exception in thread "TimerQueue"
java.lang.OutOfMemoryError: Java heap space
at java.awt.EventQueue.invokeLater(Unknown Source)
at javax.swing.SwingUtilities.invokeLater(Unknown
Source)
at javax.swing.Timer.post(Unknown Source)
at javax.swing.TimerQueue.postExpiredTimers(Unknown
Source)
at javax.swing.TimerQueue.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)
??? Error using ==> gadsplot at 114
A read error occurred while reading from lab 3. This is
causing:
java.lang.OutOfMemoryError: Java heap space

Dave,

Look at this for increasing java heap space on your system
for matlab..

Thanks I have changed that now, so hopefully won't get the
same error again. cheers.
