The Intel® Math Kernel Library (Intel® MKL) contains many routines to help you solve various numerical problems, such as multiplying matrices, solving a system of equations, and performing a Fourier transform. While many problems do not have dedicated Intel MKL routines, you can solve them by assembling the building blocks provided by Intel MKL.
The Intel Math Kernel Library Cookbook includes these recipes to help you to assemble Intel MKL routines for solving some more complex problems:
