🦋 SLARMM(3) — Library Functions Manual 🦋

🌸 NAME 🌸

Bestie, this page is for SLARMM, and its file lives at:

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/SRC/slarmm.f

✨ SYNOPSIS ✨

🧚 Functions/Subroutines 🧚

  • real function SLARMM (anorm, bnorm, cnorm) — SLARMM

💖 Function/Subroutine Documentation 💖

🌟 real function SLARMM (real anorm, real bnorm, real cnorm) 🌟

SLARMM

🔥 Purpose 🔥

Okay so SLARMM returns a factor s in (0, 1] such that these linear updates:

(s * C) - A * (s * B)  and  (s * C) - (s * A) * B

cannot overflow, where A, B, and C are matrices of conforming dimensions.

This is an auxiliary routine, so there is no argument checking. Periodt. 💅

🎀 Parameters 🎀

  • ANORM — this one is REAL. It is the infinity norm of A. ANORM >= 0. Also, the page says: “The number of rows of the matrix A. M >= 0.” Yep, keeping that line exactly as printed, bestie 🫶.
  • BNORM — this one is REAL. It is the infinity norm of B. BNORM >= 0.
  • CNORM — this one is REAL. It is the infinity norm of C. CNORM >= 0.
