Error using mex (line 206) Unable to complete successfully." What is wrong? I have copy all cpp and .h "C:\Users\nambnh\Documents\MATLAB".

Hi,
this is Microsoft Bug see here.
Since I am such a cool guy I attached the header ammintrin.h file which needs to be placed in "C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\INCLUDE\". Please rename it from ammintrin.m to ammintrin.h because one cannot upload .h files.
I hope that helps.

Looks like you have spaces in your paths. Rather than passing these arguments to the mex function via the command line "string" approach, try using the function call syntax instead so you can explicitly separate arguments even if they have spaces. And don't put your header .h files in the argument list ... they should already be included in your source code. Also I am not sure why you apparently list the same source file twice.

@James: After formatting the question, it gets clear, that the source file was not listed twice. Formatting is such useful that I cannot understand, why so many newcomers do not use the power or at least ask how to use it. Is it not usual to read a question after one has posted it?
