mex -v setup

You will probably need to install a compiler appropriate for your release. https://www.mathworks.com/content/dam/mathworks/mathworks-dot-com/support/sysreq/files/SystemRequirements-Release2018a_SupportedCompilers.pdf

Reading the help section of a failing code is obligatory. In vl_compilenn you find:

 %   Compilation on Windows with MinGW compiler (the default mex compiler in
 %   Matlab) is not supported. For Windows, please reconfigure mex to use
 %   Visual Studio C/C++ compiler.

Install the SDK7.1, which is explained in many threads here in this forum.
