# Overview

The Intel® Math Kernel Library (Intel® MKL) provides Fortran routines and functions that perform a wide variety of operations on vectors and matrices including sparse matrices and interval matrices. The library also includes fast Fourier transform (FFT) functions, as well as vector mathematical and vector statistical functions with Fortran and C interfaces.

The versions of Intel MKL intended for Windows* and Linux* operating systems also include ScaLAPACK software and Cluster FFT software for solving respective computational problems on distributed-memory parallel computers.

The Intel MKL enhances performance of the application programs that use it because the library has been optimized for latest generations of Intel® processors.
