💖 BLAS/SRC/cswap.f — bestie edition 💖

okay so this is a page from the LAPACK manual, specifically BLAS/SRC/cswap.f, and I am so excited to tell you about it because it is genuinely the most "just swap the vibes" routine to ever exist. no cap.

✨ NAME ✨

BLAS/SRC/cswap.f — it's giving "file that contains one (1) icon" 💅

🦋 SYNOPSIS 🦋

Functions/Subroutines

  • subroutine cswap (n, cx, incx, cy, incy) — CSWAP 🫶

🌸 Function/Subroutine Documentation 🌸

subroutine cswap (integer n, complex, dimension(*) cx, integer incx,
     complex, dimension(*) cy, integer incy)

CSWAP

💜 Purpose:

CSWAP interchanges two vectors. that's it. that's the whole personality. two vectors walk in, they trade places, everybody goes home. iconic behaviour honestly ✨

🎀 Parameters 🎀

  • N — N is INTEGER. number of elements in input vector(s). like, how many little guys are we swapping today, bestie?
  • CX — CX is COMPLEX array, dimension ( 1 + ( N - 1 )*abs( INCX ) ). this is one of the two vectors in the swap, and yes the dimension formula is a whole mood but it's exactly what it says 💅
  • INCX — INCX is INTEGER. storage spacing between elements of CX. basically how far apart the elements are chilling in memory 🦋
  • CY — CY is COMPLEX array, dimension ( 1 + ( N - 1 )*abs( INCY ) ). the other vector, the one CX is trading places with, no cap
  • INCY — INCY is INTEGER. storage spacing between elements of CY. same deal as INCX but for the other side 🎀

🔥 Further Details:

modified 12/3/93, array(1) declarations changed to array(*)
so this routine has history, okay? 1978 original, then a glow-up on 12/3/93 where the array(1) declarations got changed to array(*). we love an evolution arc 💖
