BLAS is a C 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.
The computer code and data files described and made available on this web page are distributed under the GNU LGPL license.
BLAS is available in a C version and a C++ version and a FORTRAN90 version and a MATLAB version.
