Re: LEVMAR with MEX

Thank you for your answer, James.

I have uncomment to line in levmar.h (29): #define HAVE_LAPACK

With LCC I get the error msg:

Here is my levmar.lib file (Windows7 32-bit, created with MS Visual Studio 10 Express): http://ifile.it/egpjb67/levmar-lib.zip
LEVMAR 2.5: http://www.ics.forth.gr/~lourakis/levmar/levmar-2.5.tgz

This library seems to be correct. Here are the results of lmdemo.exe:

I'm really desperate :( I have tried to create the levmar-MEX-file for 2 days. I need this for an nonlinear least square optimiztaion (with box constraints) in MATLAB. I don't have the optimizitaion toolbox. I have tried LMFnlsq (http://www.mathworks.com/matlabcentral/fileexchange/17534), but this is unconstrained. The second point is the speed, I think that a MEX file will be faster...

I'm really glad for any help.

Regard, PW
