Basic Linear Algebra Subroutines

Quick Reference
OG implementations in Fortran - see LAPACK
C API = LAPACKE

BLAS are defined by three papers: Basic linear algebra subprograms for {FORTRAN} usage, Lawson et al, 1979. An extended set of {FORTRAN} basic linear algebra subprograms, Dongarra et al, 1988. A set of level 3 basic linear algebra subprograms, Dongarra et al, 1990. Some BLAS-like routines (e.g., csymv, crot, csum1, icmax1) exist in LAPACK rather than the classic BLAS. These were extended by the Extra Precision BLAS (XBLAS, not documented here) https://www.netlib.org/xblas/

AO [2025-05-08 Thu] we currently prefer OpenBLAS which includes the netlib LAPACK in addition to some Extensions
