Thread Subject: How to increase the stack space available for MATLAB

Hello Everyone,

How to increase the stack space available for MATLAB.
The programs that i am running have lots of recursive
function calls. Currently the maximum recursion limit is
set to 500.
I want to increase the maximum recursion limit but before
that i must increase the stack space available for MATLAB.
Does anybody have an idea how to do it?
Please reply if anybody has a solution.

Thanks
Amogh Rajanna

The method of increasing the stack space depends upon your
operating system, which you did not mention.

The recursion limit is built in to Matlab, independant of the
stack space. You are probably not running out of stack memory:
you are probably running into a built-in Matlab counter.

How to increase stack space available for MATLAB in Windows
Vista??

Thanks

I don't know about Vista, but I found the following:

http://msdn2.microsoft.com/en-us/library/35yc2tc3(VS.80).aspx

That's the DOS/Windows command EDITBIN with the /STACK option.


Don't be surprised if it doesn't help at all. When your program
bombs out telling you your stack is too deep at -exactly- 500 levels,
you can be sure that the 500 number is programmed into Matlab, not just
chance that -exactly- 500 calls fit into the stack. And as best
I *recall*, Mathworks has said there is no way for the user to increase
the built-in recursion limit.

We give you the ability to point the recursion gun at your foot if you so
choose.

The default RecursionLimit value is 500 for all platforms except I believe
32-bit Linux, where it's set lower because I think we had problems in the
past.
