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.
Using blas
blas libraries come only in one flavor and are installed in system path. No setup required. The blas libraries provide a reference implementation, but are not highly optimized. Use for example the atlas-libraries, openblas, intel mkl, cublas, ... for optimized implementations.
