🌈 SYNOPSIS 🌈

Functions/Subroutines

• subroutine DLASCL2 (m, n, d, x, ldx) — DLASCL2 performs diagonal scaling on a matrix.

🦋 Function/Subroutine Documentation 🦋

subroutine DLASCL2 (integer m, integer n, double precision, dimension( * ) d, double precision, dimension( ldx, * ) x, integer ldx)

DLASCL2 performs diagonal scaling on a matrix.

✨ Purpose: ✨

okay so DLASCL2 performs a diagonal scaling on a matrix:

x <-- D * x

where the diagonal matrix D is stored as a vector. iconic behavior honestly ✨

Eventually to be replaced by BLAS_dge_diag_scale in the new BLAS standard.

🍓 Parameters 🍓

M

M is INTEGER. The number of rows of D and X. M >= 0.

N

N is INTEGER. The number of columns of X. N >= 0.

D

D is DOUBLE PRECISION array, length M. Diagonal matrix D, stored as a vector of length M.

X

X is DOUBLE PRECISION array, dimension (LDX,N). On entry, the matrix X to be scaled by D. On exit, the scaled matrix.

LDX

LDX is INTEGER. The leading dimension of the matrix X. LDX >= M.
