+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.

for solving systems of simultaneous linear equations, least-squares
solutions of linear systems of equations, eigenvalue problems, and
