SSWAP(3)

💅 SSWAP(3)

ok so this is the manual page for SSWAP — she lives in the LAPACK BLAS zone and she's here to swap ur vectors bestie ✨

ngl the "name" on the original is literally just the whole file path, iconic behavior honestly:

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/BLAS/SRC/sswap.f

that's it, that's the name 🎀

✨ SYNOPSIS ✨

Functions/Subroutines

• subroutine SSWAP (n, sx, incx, sy, incy) — SSWAP 💫

---

🦋 Function/Subroutine Documentation

subroutine SSWAP (integer n, real, dimension(*) sx, integer incx, real, dimension(*) sy, integer incy)

SSWAP 🌸

Purpose:

!>
!>    SSWAP interchanges two vectors.
!>    uses unrolled loops for increments equal to 1.
!>

ok so real talk: SSWAP interchanges two vectors — like, swaps them, trades their whole fit 💅 and lowkey it uses unrolled loops for increments equal to 1, which is the little speed hack, iykyk ⚡

Parameters

• N

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

N is INTEGER — it's how many elements are in ur input vector(s) 🍓

• SX

!>          SX is REAL array, dimension ( 1 + ( N - 1 )*abs( INCX ) )
!>

SX is a REAL array, dimension ( 1 + ( N - 1 )*abs( INCX ) ) — that's the exact size, no cap 🫶

• INCX

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

INCX is INTEGER — the storage spacing between elements of SX 👑

• SY

!>          SY is REAL array, dimension ( 1 + ( N - 1 )*abs( INCY ) )
!>

SY is a REAL array, dimension ( 1 + ( N - 1 )*abs( INCY ) ) — yes it uses INCY, not a typo, she's her own girl 💜

• INCY

!>          INCY is INTEGER
!>         storage spacing between elements of SY
!>

INCY is INTEGER — the storage spacing between elements of SY 🌈

so jack dongarra, linpack, 3/11/78 — and then it got modified 12/3/93, when the array(1) declarations changed to array(*). a glow-up for the ages 💅

and that's the whole vibe!! LAPACK, Version 3.12.0, from /home/abui...SRC/sswap.f(3) — okay bye bestie, go swap some vectors, slay 💖🌸🧚‍♀️
