💅 SRC/clascl2.f(3) 💅

okay bestie, this is the Library Functions Manual page for SRC/clascl2.f(3) — title and manual name folded right in at the top, no weird header-line copy-paste energy. Let’s get into it. 🫶

🌸 NAME 🌸

SRC/clascl2.f — that’s it, that’s the name. iconic.

✨ SYNOPSIS ✨

🧸 Functions/Subroutines 🧸

  • subroutine clascl2 (m, n, d, x, ldx) — CLASCL2 performs diagonal scaling on a matrix.

👑 Function/Subroutine Documentation 👑

subroutine clascl2 (integer m, integer n, real, dimension( * ) d, complex, dimension( ldx, * ) x, integer ldx)

CLASCL2 performs diagonal scaling on a matrix.

💫 Purpose 💫

the details are sacred, so here’s the exact Purpose block:

!>
!> CLASCL2 performs a diagonal scaling on a matrix:
!>   x <-- D * x
!> where the diagonal REAL matrix D is stored as a matrix.
!>
!> Eventually to be replaced by BLAS_cge_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 REAL array, length M; diagonal matrix D, stored as a vector of length M.
  • X — X is COMPLEX 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.
