SRC/clarscl2.f(3)

🎀 NAME 🎀

SRC/clarscl2.f — bestie, this is the page, and it's chilling in the Library Functions Manual. It's giving Fortran subroutine realness from LAPACK, no cap.

✨ SYNOPSIS ✨

🌟 Functions/Subroutines 🌟

• subroutine clarscl2 (m, n, d, x, ldx) — CLARSCL2 performs reciprocal diagonal scaling on a matrix. Slay.

💅 Function/Subroutine Documentation 💅

🦋 subroutine clarscl2 🦋

subroutine clarscl2 (integer m, integer n, real, dimension( * ) d, complex, dimension( ldx, * ) x, integer ldx)

CLARSCL2 performs reciprocal diagonal scaling on a matrix.

🎀 Purpose 🎀

Okay so the purpose is literally right here, and I'm keeping the doc-comment energy intact:

!>
!> CLARSCL2 performs a reciprocal diagonal scaling on a matrix:
!>   x <-- inv(D) * x
!> where the REAL diagonal matrix D is stored as a vector.
!>
!> Eventually to be replaced by BLAS_cge_diag_scale in the new BLAS
!> standard.

🍓 Parameters 🍓

• M — M is INTEGER; it's the number of rows of D and X, and M >= 0.
• N — N is INTEGER; it's the number of columns of X, and N >= 0.
• D — D is REAL array, length M; this is the diagonal matrix D, stored as a vector of length M.
• X — X is COMPLEX array, dimension (LDX,N); on entry, it's the matrix X to be scaled by D, and on exit it's the scaled matrix.
• LDX — LDX is INTEGER; it's the leading dimension of the matrix X, and LDX >= M.
