blas_top(3)

Hiii bestie 💖 welcome to blas_top(3), the BLAS landing page from the Library Functions Manual. Buckle up, because this one is short but iconic. ✨

💖 NAME 💖

blas_top — BLAS. That’s the whole name, and it’s giving gateway-to-the-BLAS-universe energy. 🌈

✨ SYNOPSIS ✨

🎀 Topics 🎀

• 🌸 Scalar operations
• 💅 Level 1 BLAS: vector ops
• 🦋 Level 2 BLAS: matrix-vector ops
• 👑 Level 3 BLAS: matrix-matrix ops

🦋 Detailed Description 🦋

BLAS are defined by three papers, and yes, bestie, we’re listing all three because receipts matter:

• 📄 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) at https://www.netlib.org/xblas/. 🧚
