The Intel® Math Kernel Library (Intel® MKL) provides broad support for Fortran and C/C++ programming. However, not all function domains support both Fortran and C interfaces. For example, LAPACK has no C interface. You can call functions comprising such domains from C using mixed-language programming.
If you want to use LAPACK or BLAS, which support Fortran, in the Fortran 95 environment, additional effort may be initially required to build compiler-specific interface libraries and modules from the source code provided with Intel MKL.
