Abeera - have you looked at the link http://www.mathworks.com/help/matlab/matlab_external/calling-lapack-and-blas-functions-from-mex-files.html?

MATLAB ships with BLAS and LAPACK libraries. E.g., on Windows for 64-bit Microsoft compilation, you can typically find them here:

lib_blas   = [matlabroot '\extern\lib\win64\microsoft\libmwblas.lib']
lib_lapack = [matlabroot '\extern\lib\win64\microsoft\libmwlapack.lib']

To link your code with these, you can just do this:

cfilename = 'my_mex_name.c';
mex(cfilename,lib_blas,lib_lapack);
