What happened when you commanded

mex -setup

at the MATLAB command window?

Answer 2

it shows this,

Welcome to mex -setup. This utility will help you set up a default compiler. For a list of supported compilers, see http://www.mathworks.com/support/compilers/R2011b/win64.html

Please choose your compiler for building MEX-files:

Would you like mex to locate installed compilers [y]/n?

[Walter Roberson]

And when you told it to go ahead and locate the installed compilers?

[zewl elena]

it shows this:

Error using mex (line 206) Unable to complete successfully.

Hmmm. Have you installed the 64 bit compiler and SDK 7.1 as indicated in the link mentioned above, http://www.mathworks.com/support/compilers/R2011b/win64.html

Please show the entire transcript of your attempt to mex -setup . Perhaps someone will recognize something in the details.
