Sometimes it is confusing knowing what is a low-level BLAS. I am currently struggling a lot trying to compile the Fortran CUBLAS example (Fortran_Cuda_Blas.tgz) under Windows XP with Microsoft Visual Studio 2005 (using Intel Fortran Compiler). oneMKL provides many options for creating code for multiple processors and operating systems, compatible with different compilers and third-party libraries, and with different interfaces.

Fortran does things differently, storing elements of a matrix in column-major order. mkl_mmx_c directory. #inthecalling(sub)program. For example, for the class which represents multiplication subroutines, there are attributes to de-termine which specific multiplication subroutine to be called, attributes to pass the multiplication coefficient, attributes to determine how to reorder the indices in the multiplication component quantities, etc. You can call LAPACK and BLAS functions from Fortran MEX files. columns (for column major storage) in memory.
