Matlab internal error problem

Hi all,

       when I'm trying to run my program of NSCT for  directional level greater than 16 , I'm getting an error of

"*MATLAB has encountered an internal error and needs to close the program immediately"*

and exit matlab. the error log details as follows.

This error was detected while a MEX-file was running. If the MEX-file
is not an official MathWorks function, please examine its source code
for errors. Please consult the External Interfaces Guide for information
on debugging MEX-files.

If it is an official MathWorks function, please
follow these steps to report this problem to The MathWorks so we
have the best chance of correcting it:

The next time MATLAB is launched under typical usage, a dialog box will
open to help you send the error log to The MathWorks. Alternatively, you
can send an e-mail to [e-mail] with the following file attached:
    C:\DOCUME~1\user1\LOCALS~1\Temp\matlab_crash_dump.2436

If the problem is reproducible, please submit a Service Request via:
    http://www.mathworks.com/support/contact_us/ts/help_request_1.html

A technical support engineer might contact you with further information.

Thank you for your help. MATLAB may attempt to recover, but even if recovery appears successful,
we recommend that you save your workspace and restart MATLAB as soon as possible.

How to solve the problem to get output for greater than level 16 when it is actually possible.

Answer 1

[Walter Roberson]

Crashes should be reported to Mathworks technical support.

Answer 2

[Kaustubha Govind]

You may want to contact the author of the toolbox (this doesn't look like a function from MathWorks toolboxes). The crash is occuring in the MEX-function 'zconv2'.

Alternatively, if you have access to the source code, you could try debugging the file.

[Razia]

I tried in another system and I'm getting output upto 128 levels. but 256 level same error encountered. Does it differ with system speed or compiler type?

[Walter Roberson]

It might vary with compiler used to build the .mex32, but the first thing I would look for is the possibility that you ran out of memory and that the other system had more memory.
