sse4a intruction set not enabled when I try to compile MatConvNet. I'm running the program in MATLAB R2015a with NVidia GT720 on Intel i7 Windows 8.1. I have installed the c/c++ compiler also. The problems start when I run the vl_compilenn. Thanks.

Error using mex pooling_cpu.cpp C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\INCLUDE\ammintrin.h(28) : fatal error C1189: #error : "SSE4A instruction set not enabled"

It would not surprise me if VS 2010 did not understand SSE4A instructions. You might need to use a later compiler.
