MATLAB: Help with creating a MEX file in MATLAB from multiple C++ Source codes

interface matlab with c++link errorMATLABMATLAB C/C++ Math Librarymex files

I am trying to create a MEX file in MATLAB with multiples C++ source codes in .cpp and .h extensions. The C++ source codes builds fine with no errors in Microsoft Visual C++ 2010 professional and i have created a static library of .lib file All source code files and static library of functions are located in my MATLAB current folder path In MATLAB i have selected my default compiler as MS Visual C++ Professional 2010 and i am using the following syntax in MATLAB mex -v [list of C++ source code files i.e. .cpp and .h files] -l[static library name] -L.
I get a link error in MATLAB as; LINK : error LNK2001: unresolved external symbol mexFunction C:\Users\abo09001\AppData\Local\Temp\mex_Ko9pXP\templib.x : fatal error LNK1120: 1 unresolved externals
I do not know how to program in C++ but i am relatively ok in MATLAB. Any help with the error will be appreciated.

All MEX-functions need to have an entry-point named mexFunction with a specific prototype. I would recommend that you read the section Creating a Source MEX-File to help you get started.
