MATLAB: Is MATLAB R2012b sluggish and why does the UI hang occassionally

MATLABslowunresponsive

When I enter the following line at the command prompt,

stem(true(2664,1))

MATLAB becomes unresponsive.

Best Answer

With the new interface in R2012b, MATLAB uses more Java Heap Space (graphics components etc.) by default. With the default Java Heap Space the UI may not have enough memory.

As a first step for addressing R2012b sluggishness, please raise the Java Heap Space a fair amount. On my system with 8Gb of RAM running Windows 7x64 Sp1, I have found about 1000MB to be really helpful. Please go to:

Home Tab -> Preferences -> General -> Java Heap Space, and bump it up a bit. Apply the changes and restart MATLAB

MATLAB: Does MATLAB crash when using xmlread with large files

One of the reasons for XMLREAD to fail when reading large files could be the lack of enough Java Heap Memory. The amount of Java Heap memory available to MATLAB can be increased and this can be done in the following way, in the MATLAB Desktop Window:

For versions of MATLAB R2010a and above use -

File -> Preferences -> General -> Java Heap Memory.

Move the slider to a desirable location.

For versions of MATLAB prior to R2010a, refer to the link below-
