SRC/slarscl2.f(3)

💖 NAME 💖

okay so this is the page for SRC/slarscl2.f, straight out of the Library Functions Manual. bestie, it's all about the slarscl2 subroutine — the little icon that does reciprocal diagonal scaling on a matrix. ✨

✨ SYNOPSIS ✨

Functions/Subroutines

• subroutine slarscl2 (m, n, d, x, ldx) — SLARSCL2 performs reciprocal diagonal scaling on a matrix. 💅

🎀 Function/Subroutine Documentation 🎀

subroutine slarscl2 (integer m, integer n, real, dimension( * ) d, real, dimension( ldx, * ) x, integer ldx)

SLARSCL2 performs reciprocal diagonal scaling on a matrix. no cap, that's the whole vibe. 🦋

💜 Purpose

           !>
           !> SLARSCL2 performs a reciprocal diagonal scaling on a matrix:
           !>   x <-- inv(D) * x
           !> where the diagonal matrix D is stored as a vector.
           !>
           !> Eventually to be replaced by BLAS_sge_diag_scale in the new BLAS
           !> standard.
           !>

🌸 Parameters

• M — it's an INTEGER, bestie. The number of rows of D and X. M >= 0. 🫶
• N — also an INTEGER. The number of columns of X. N >= 0. 🌟
• D — a REAL array, length M. Diagonal matrix D, stored as a vector of length M. 💅
• X — a REAL array, dimension (LDX,N). On entry, the matrix X to be scaled by D. On exit, the scaled matrix. ✨
• LDX — an INTEGER. The leading dimension of the matrix X. LDX >= M. 🎀
