BLAS
Basic Linear Algebra Subprograms


BLAS is a FORTRAN77 library which contains the Basic Linear Algebra Subprograms (BLAS) for level 1 (vector-vector operations), level 2 (matrix-vector operations) and level 3 (matrix-matrix operations), for single precision real arithmetic, double precision real arithmetic, single precision complex arithmetic, and double precision complex arithmetic.

For the contents of the library, refer to the individual components. This page exists primarily to explain how the unified BLAS library is created from the pieces.
