Error using mex
MEX cannot find library 'mwblas' specified with the -l option.
MEX looks for a file with one of the names:
libmwblas.lib
mwblas.lib
Please specify the path to this library with the -L option.
Has anyone seen this before?
I'm trying to run vl_compilenn from a neural net pack, and I get this when I compile. Any ideas?

Did you use the structure shown at http://www.mathworks.com/help/matlab/matlab_external/calling-lapack-and-blas-functions-from-mex-files.html ?

Thia error occurs when you try to use libmwblas.dll with a .cpp file, while everything is correct with .c file. Just try
mex '-LC:\Program Files\MATLAB\R2017b\extern\lib\win64\microsoft' -lmwblas your_file.cpp
