Have you tried deleting/renaming the old .mexw64 file?

MATLAB: Do I receive a “LINK : error LNK2001: unresolved external symbol mexFunction” error when I attempt to mex a C++ source file using MATLAB 7.8 (R2009a)

The error received is a linker error which indicates that the C++ source file that is being MEXed does not contain the MEX gateway function "mexFunction".

To create a MEX file using source code that is present in multiple source files, provide all the source files as input to the MEX function. For example, if you have the following source files:

 fileContaininingMEXGateway.cpp
 sourceFile1.cpp
 sourcefile2.cpp

the MEX command to be used to create a a MEX file is shown below:

mex -v fileContaininingMEXGateway.cpp sourceFile1.cpp sourcefile2.cpp
