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.

[Walter Roberson]

Above, between Friedrich's Answer and the start of the Comments there is "ammintrin.m". That is a link. You can use your browser to save the content of the link to a file.

If I try to copy paste the file into the folder it doesn't let you do that in Windows 7..The whole directory crashes.

[Walter Roberson]

Could you explain more what it means for a directory to crash?

[Grey Kuling]

Thank you so much! This was extremely helpful!

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.

[Jan]

@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?

Error using mex

Hi I am unable to compile gco library in MATLAB2016a in windows. Could someone please help and explain me to get rid of this error?

[Walter Roberson]

Looking at those messages, it appears to me that on line 8 of gco_matlab.cpp that it attempts to define mwSize and on line it attempts to define mwIndex, but that those are already defined by the tmwtypes.h header file. If I am correct, then comment out the typedef at lines 8 and 9 of gco_matlab.cpp
