You are of course correct with all your points. However, on the device management side, some tricks can help like: 1- Give higher priority to Matlab.exe task.

Remember that increasing the size of the Java heap may correspondingly decrease the amount of space available for MATLAB arrays. It is really annoying. This takes much more time and is less effective to debug than for Matlab code.

Matlab and PLS_Toolbox In Matlab 2009b, and earlier versions, you increase the allocated Java heap space by creating a file named "java.opts" in your \Program Files\MATLAB\R2009b\bin\win32\ directory (or \win64 if you I know Matlab has a delete function, and I didn't know when/if it would be helpful to use this function to save memory? Matlab Heap Data Structure The following table shows the default settings MATLAB uses for versions of the JVM: JVM Initial Heap Size Max Heap Size 1.6.0 -Xms64m -Xmx128m (32-bit) -Xmx196m (64-bit) 1.5.0 -Xms64m -Xmx96m (32-bit)

Java.opts Matlab Example Notwithstanding all the correct reservations you have raised above, I believe that JVM's own instrumentation gives the closest possible estimate of the actual object size. Other thing, is disable java (which is a memory hogger) like is and this works better if you are only analyzing the data not using visualizations. java matlab memory-management share|improve this question asked Apr 6 '14 at 16:24 Maggick 2851318 add a comment| 1 Answer 1 active oldest votes up vote 1 down vote See this question.
You can do this by submitting your license.dat file that you find here: [COMSOL]/license/license.datwhere [COMSOL] is the COMSOL Multiphysics installation directory. It only goes to 35 megs or so, and I'm dealing with a few huge objects of several gigs.

Take care to match the upper and lower case characters in that line and have no spaces between any characters. A passcode looks like this: XXXXXXXXXX-XXXX-XXXXXX-XXXXXXX-XXXXXXXXX. Here is an example: http://undocumentedmatlab.com/blog/internal-matlab-memory-optimizations Hope this helps! http://rsmasters.net/java-heap/java-out-of-memory-error-matlab.html Matlab and Solo's engine use their own Java virtual machine (JVM) and they both allocate a certain amount of memory (or heap space) to the JVM.

Feb 28, 2013 Anil Thota · Florida International University The best way is to preallocate the memory if you know the size of matrices that you working. Why did you enter JavaMemHeapMax=I190000 when you said you had 192GB? However this value can be queried with the following command: max = java.lang.Runtime.getRuntime.maxMemory max = 130875392 I wrote awhile ago about how MATLAB manages its Java memory (including the distinction between
Use "pack" command to compress variables in memory and make more free space. Email: Password: Remember me Did you forget your password? You can also use "zeros" function to predetermine huge the variables/matrixes. No problem.
What does a midi-chlorian look like? In fact, in some circumstances it might make the problem worse, as you are allotting more memory for the java heap and now have less memory available for, say, creating large Jonas replied on April 26th, 2010 6:12 pm UTC : 3 of 12 Nice feature. Currently, whos returns zero size for Java objects.
It is simply frustrating for me not to be able to profile Java memory usage as easily as Matlab memory or CPU usage. I used this trick with my older laptop which was 32 bits OS and used to have a profound impact on applications performance. I have the GUI maxed out, but it really doesn't seem to do anything (I get out of memory errors).
