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