Can someone offer a solution or send me the header so I can just put it in the same folder? (I could not find this header anywhere on my hard drive. Many thanks.

I'm using MATLAB 2014a and Microsoft SDK 7.1 on Windows 7 64 bit

If you have the distcomp (Distributed computation) Toolbox, you should have the .h under

\MATLAB\R2014a\toolbox\distcomp\gpu\extern\include\gpu

hi I am using ubuntu and I found mxGPUArray file under

/usr/local/MATLAB/R2019b/toolbox/parallel/gpu/extern/include/gpu

But I get an error as

/matconvnet-1.0-beta24/matlab/src/bits/datamex.hpp:19:28: fatal error: gpu/mxGPUArray.h: No such file or directory

#include "gpu/mxGPUArray.h"

Could you please suggest me a work around for this.

[Mohamed Hassan]

you can make a symbolic link from parallel to distcomp
