Hi,

I have a mex file which i run from matlab. It works fine. However, if i try to run it multiple times in a loop ( about 25 times) i get "Unexpected Standard exception from MEX file. What() is:bad allocation" What is this error and what do i need to look for in order to fix it ?

Please post the corresponding part of the code. It is impossible to fix code, which is not known.

a. Yes, I am allocating memory within the MEX function.

b. The loop is outside the MEX function (iterating in MATLAB, not in the MEX).

when you ask for code snippet than i can understand you mean

I think I solved it - I forgot to delete some arrays i defined with pointers and using "new". so the block of memory was never released between runs. thanks anyway.
