Hi, I am trying to run mex files on matlab, I got intel fortran to work (somehow) but now I am getting an error message when running the mex command. Here is what I get (sorry for some german terms in there), any idea what could be wrong?

mex  -v  yprimef.F

Seems like a permissions/UAC issue. Are you running the command from a directory that you have write access to? Also, try copying yprimef.F to a location in your home directory so that the MEX command doesn't attempt to write to the MATLAB installation root (inside C:\Program Files). If that still doesn't work, try starting MATLAB as Administrator and run the command.

actually, this error message is probably related to my other post:

http://mathworks.com/matlabcentral/answers/37926-intel-fortran-matlab-2012a#answer_47312

I change some references in the mexopts.bat file that matlab uses to link to the compiler. Turns out that it was partially correct I guess as I did not get the error message 'can't find compiler' anymore but the one that I posted above.

Note, when I search for compiler I get offered

[1] Microsoft Visual C++ 2010 in C:\Program Files (x86)\Microsoft Visual Studio 10.0

If I choose that option then I can run mex yprime.c just fine. Unfortunately I need to get intel fortran to run but sth appears to be wrong.

thanks for the help.

here is my mexopts.bat file:

thanks for the advice. I ran it as administrator and it didn't help. When I set it to c++ compiler via mex -setup and let matlab search, it finds it, i choose it and I can run mex yprime.c without problem. Thus this must be a different issue with the intel fortran

Oops, just noticed the "Unresolved external symbol" error in your question. Sorry, this missed my eye because it was in German. It looks like the issue is not the compiler, but your MEX-file yprimef.F - is there a function called mexFunction defined in it? This function is required as an entry-point in MEX-function.
