💖 NAME 💖

okay so this page is SRC/zlascl2.f(3), and it's hanging out in the Library Functions Manual like the main character it is. The actual name of the file/page is literally:

SRC/zlascl2.f

✨ SYNOPSIS ✨

🌈 Functions/Subroutines 🌈

  • subroutine zlascl2 (m, n, d, x, ldx) — bestie, this is the one: ZLASCL2 performs diagonal scaling on a matrix. 💅

🎀 Function/Subroutine Documentation 🎀

Here's the full signature, copied exactly so there's zero typo chaos:

subroutine zlascl2 (integer m, integer n, double precision, dimension( * )
     d, complex*16, dimension( ldx, * ) x, integer ldx)

And the one-liner vibe is literally: ZLASCL2 performs diagonal scaling on a matrix. ✨

🌸 Purpose 🌸

okay so ZLASCL2 performs a diagonal scaling on a matrix:

x <-- D * x

where the DOUBLE PRECISION diagonal matrix D is stored as a vector. 🫶

Eventually to be replaced by BLAS_zge_diag_scale in the new BLAS standard. ikyk. 🦋

🧚 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 COMPLEX*16 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. ⭐

xoxo, bestie 💖 — this footer energy is LAPACK · Version 3.12.0 · source SRC/zlascl2.f(3). The page didn't print a separate date, so I'm not inventing one; that's the whole sign-off. periodt. 💅
