Compiling CUDA files with mex -v mexGPUExample.cu

Im trying to compile CUDA files into mex.

Matlab ships with an example CUDA file located in matlabfolder\toolbox\distcomp\gpu\extern\src\mex, but when I try to compile it by typing:

mex -v  mexGPUExample.cu

I get:

Error using mex

Im using the VS2013 cuda7.5 and Windows SDK 8.1A ,why have this problem?

You can't compile this file with mex, it must be compiled with mexcuda.

I compile the file with mexcuda, it also has error:

Error using mex
No supported compiler or SDK was found. You can install the freely
available MinGW-w64 C/C++ compiler; see Install MinGW-w64 Compiler.
For more options, see 
http://www.mathworks.com/support/compilers/R2015b/win64.html.

should I install the MinGW-w64 C/C++ compiler ?

[Joss Knight]

No, because that compiler isn't supported by the CUDA compiler. Can you give me the verbose output from mexcuda? I need to see why it's not picking up your Visual Studio installation.
