Basic Linear Algebra Subroutines (BLAS)
http://www.netlib.org/blas/faq.html
Core routines used by LAPACK (Linear Algebra Package) and elsewhere. Generally optimized for particular machine architectures, cache hierarchy.
The subroutines are categorized to three levels.
- Level 1: Scalar and vector operations
- Level 2: Matrix-vector operations
- Level 3: Matrix-matrix operations
Subroutine names start with:
- S: single precision
- D: double precision
- C: single precision complex
- Z: double precision complex
Examples:
- DDOT: dot product of two vectors
- DGEMV: matrix-vector multiply, general matrices
- DGEMM: matrix-matrix multiply, general matrices
- DSYMM: matrix-matrix multiply, symmetric matrices
