getting error "fatal error C1083: Cannot open include file: 'mex.h': No such file or directory" when trying to create mex

For some reason mex.h is not being found. I am using microsoft visual c++ 2010 express and matlab 2011b. I have done the mex -setup, and set visual c++ express as my compiler. But cannot figure out why it is not working.

[Kaustubha Govind]

Could you try compiling with the -v flag (verbose mode) and paste the full output of the mex command here?

I can't read through all of that output. How, exactly, are you trying to compile the file? Are you compiling with a bat file outside of MATLAB, and not with the mex command at the MATLAB command line?
