yprime.c to mex compile, error using mex at 208

Hi all

I'm using Matlab 2011a 64 bit and Microsoft Visual Studio 2010 as a compiler. If I try to compile yprime to a mex file i get following error:

Can please anyone advise?

Thank you! Edgar

Could you try running MATLAB as administrator and try again (if you're on Windows 7)? Also, try first going into C:\test and then compiling using "mex yprime.c".

Thank you for your help, this was actually the problem. Yeah the error message is really not indicating that this is the problem. Have a nice weekend!

I assume Kaustubha's 2nd idea "cd('C:\test')" could solve the problem, if you do not have write permissions to the current folder. But the error message is not really helpful.
