Inner Product Outer Product Matrix-Vector Product Matrix-Matrix Product Basic Linear Algebra Subprograms

Basic Linear Algebra Subprograms (BLAS) are building blocks for many other matrix computations BLAS encapsulate basic operations on vectors and matrices so they can be optimized for particular computer architecture while high-level routines that call them remain portable BLAS offer good opportunities for optimizing utilization of memory hierarchy Generic BLAS are available from netlib, and many computer vendors provide custom versions optimized for their particular system
