Test scripts with mex fails

[fordanic]

Whenever I try to run any of the test scripts making use of a mex-implementation, they crash with the following error message:

Error using asetsBinaryMF2D_mex

No issues encountered during compilation.

Any suggestions for what the issue might be?
Thanks,

Hi Daniel,
looks like you are trying to allocate a lot of memory for the graph. When passing images of a certain size the graph is constructed with a node per pixel, so you will need to check two things: 1) did you pass the correct input array dimensions (see pars = [r; c; maxIter; convErrBound2D; 0.2; 0.16]; where r is rows and c is columns) and 2) do you have enough memory?

I'd check if the matlab code works (i.e. comment out the mex call) first and take it from there. If you need help feel free to drop me an email.

The errors occur when I run the test scripts as is. If I comment out the use of the mex files everything seem to be working fine.

Can you let me know of the Matlab, OS, compiler version, etc so I can try and reproduce it?
