%description

The BLAS (Basic Linear Algebra Subprograms) are routines that provide standard
building blocks for performing basic vector and matrix operations. The Level 1
BLAS perform scalar, vector and vector-vector operations, the Level 2 BLAS
perform matrix-vector operations, and the Level 3 BLAS perform matrix-matrix
operations. Because the BLAS are efficient, portable, and widely available,
they are commonly used in the development of high quality linear algebra
software, LAPACK for example.
