BLAS/SRC/csscal.f(3)

💅 BLAS/SRC/csscal.f — like, the whole manual, bestie

okay so this is the csscal page from the BLAS docs, living under BLAS/SRC/csscal.f(3) in the Library Functions Manual. it's short, it's sweet, it slays, let's go 🎀

---

✨ NAME ✨

BLAS/SRC/csscal.f — that's the file, that's the name, no notes 💅

---

✨ SYNOPSIS ✨

🌸 Functions/Subroutines

• subroutine csscal (n, sa, cx, incx) — this is the one, this is the icon, this is CSSCAL 🫶

---

✨ Function/Subroutine Documentation ✨

💖 subroutine csscal (integer n, real sa, complex, dimension(*) cx, integer incx)

CSSCAL — say it with me 👑

Purpose:

!>
!>    CSSCAL scales a complex vector by a real constant.
!>

so literally the whole job is: complex vector in, real constant applied, scaled vector out. that's it, that's the vibe check and it passed 🌈

Parameters

• N — and the docs go:

!>          N is INTEGER
!>         number of elements in input vector(s)
!>

• SA — the docs say:

!>          SA is REAL
!>           On entry, SA specifies the scalar alpha.
!>

• CX — the docs say:

!>          CX is COMPLEX array, dimension ( 1 + ( N - 1 )*abs( INCX ) )
!>

• INCX — the docs say:

!>          INCX is INTEGER
!>         storage spacing between elements of CX
!>

🫶 note bestie: CX is declared dimension(*) in the signature but the docs describe it as dimension ( 1 + ( N - 1 )*abs( INCX ) ) — that's not a typo, that's literally how it's written. don't come for me, I'm just the messenger 💀

history lesson moment 📜 — jack dongarra, linpack, 3/11/78. then modified 3/93 to return if incx .le. 0. and then modified 12/3/93, array(1) declarations changed to array(*). glow-ups across the decades, we love to see it ✨

sign-off era: this lil beauty is from LAPACK, Version 3.12.0, and the page footer date is BLAS/SRC/csscal.f(3) — okay that's the footer line, not a date, but you get the vibe 🎀 mwah, go scale some complex vectors by a real constant, periodt 💜
