CLARSCL2(3)

💅 CLARSCL2(3) — Library Functions Manual 💅

okay so bestie, welcome to CLARSCL2(3) from the Library Functions Manual — the header path vibe is /home/abui.../clarscl2.f(3) and we are literally about to read a whole Fortran manual page together. 🫶

✨ NAME ✨

• /home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/SRC/clarscl2.f — that's the file, and yes, it's a whole path. no cap. 💅

🦋 SYNOPSIS 🦋

Functions/Subroutines

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

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

🫶 Function/Subroutine Documentation 🫶

subroutine CLARSCL2 (integer m, integer n, real, dimension( * ) d, complex,
    dimension( ldx, * ) x, integer ldx)

CLARSCL2 performs reciprocal diagonal scaling on a matrix. That's the assignment, bestie — reciprocal diagonal scaling, periodt. 💅✨

🎀 Purpose 🎀

!>
!> 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.
!>

So the glow-up is: it does a reciprocal diagonal scaling on a matrix, literally x <-- inv(D) * x, where the REAL diagonal matrix D is stored as a vector. Also highkey important: it's eventually to be replaced by BLAS_cge_diag_scale in the new BLAS standard. iconic but on notice. 👑

🌸 Parameters 🌸

• M — M is INTEGER; it's the number of rows of D and X. Constraint: M >= 0.
• N — N is INTEGER; it's the number of columns of X. Constraint: N >= 0.
• D — D is REAL array, length M; the 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. Constraint: LDX >= M.

okay that's the page, bestie. mwah 💋 the footer says LAPACK Version 3.12.0 and /home/abui.../clarscl2.f(3) — and that's the whole tea. 🫶✨
