✨ BLAS/SRC/sswap.f(3) ✨

okay bestie, welcome to the LAPACK manual page for BLAS/SRC/sswap.f — yes the whole file is the star here, no cap 💅

🎀 NAME 🎀

BLAS/SRC/sswap.f

like. that's literally it. that's the name. iconic behavior honestly 🦋

🌸 SYNOPSIS 🌸

Functions/Subroutines

  • subroutine sswap (n, sx, incx, sy, incy) — aka SSWAP, the moment we've all been waiting for ✨

💖 Function/Subroutine Documentation 💖

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

SSWAP 🫶

⭐ Purpose ⭐

ngl the job description here is so clean:

SSWAP interchanges two vectors. it uses unrolled loops for increments equal to 1. 🔥

that's it. swap city. two vectors walk in, two vectors walk out with each other's whole identity. main character energy fr fr 👑

🦋 Parameters 🦋

  • N — N is INTEGER, and it's the number of elements in input vector(s). so like, how many besties are we swapping. the headcount. the roster size. periodt 💜
  • SX — SX is REAL array, dimension ( 1 + ( N - 1 )*abs( INCX ) ). one of the two vectors in this whole exchange, she's got a dimension formula and she's not afraid to use it 🌈
  • INCX — INCX is INTEGER, and it's the storage spacing between elements of SX. like how far apart each element is standing from the next one. personal space, but make it integer 🎀
  • SY — SY is REAL array, dimension ( 1 + ( N - 1 )*abs( INCY ) ). the other vector!! the swap partner!! the one SX is about to trade places with entirely 💫
  • INCY — INCY is INTEGER, and it's the storage spacing between elements of SY. same deal as INCX but for the other girlie. every element gets her own spacing ok 🙈

🌟 Further Details: 🌟

the lore drop, the origin story:

jack dongarra, linpack, 3/11/78.
modified 12/3/93, array(1) declarations changed to array(*)

so it's giving vintage 1978 jack dongarra linpack energy, and then a lil glow-up on 12/3/93 where array(1) declarations got changed to array(*). a makeover. a rebrand. we love to see it ✨
