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?

This is the file I'm trying to run. I compiled it using a more verbose level and I got this message,
Set INCLUDE = C:\TDM-GCC-64\\include;
Set LIB = C:\TDM-GCC-64\\lib;;
Set MW_TARGET_ARCH = win64;
Set LIBPATH = C:\Program Files\MATLAB\R2015b\extern\lib\win64;

For some reason it gets to this line, and errors out. Do you have any idea what would cause this?

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
