I am getting a linker error with VC++2008

unresolved external symbol _mxCreateNumericMatrix_730

Which I take to mean that the definition in "matrix.h" is giving me the unresolved reference. Perhaps it should be something other than 730? I am wondering if someone could give me a clue?

Code;

mxArray *mexarray =mxCreateNumericMatrix(m, n,mxSINGLE_CLASS, mxREAL);

I'm currently using MATLAB 7.10.0(R2010a) Thanks!

Are you compiling using the MEX command, or directly in VC++? If directly in Visual Studio, are you linking against $matlabroot\extern\lib\$arch\microsoft\libmx.lib ($matlabroot=MATLAB installation directory, $arch is win32 or win64 depending on your system)? Also, make sure that if you have a 64-bit installation of MATLAB, your Visual Studio project is configured for an x64 target.
