Quote from `` BLAS Frequently Asked Questions''
(http://www.netlib.org/blas/faq.html):

`` 1.1) What are the BLAS?

The BLAS (Basic Linear Algebra Subprograms) are high quality "building 
block" routines for performing basic vector and matrix operations. Level 
1 BLAS do vector-vector operations, Level 2 BLAS do matrix-vector 
operations, and Level 3 BLAS do matrix-matrix operations. Because the 
BLAS are efficient, portable, and widely available, they're commonly 
used in the development of high quality linear algebra software, LINPACK 
and LAPACK for example.''
