✨ NAME ✨

Ok so this page is BLAS/SRC/dswap.f(3) from the Library Functions Manual — and the name in the spotlight is BLAS/SRC/dswap.f. That's the whole name section, bestie. Slay. 🎀

🌸 SYNOPSIS 🌸

🧚 Functions/Subroutines

  • subroutine dswap (n, dx, incx, dy, incy) — DSWAP
subroutine dswap (n, dx, incx, dy, incy)
    DSWAP

💖 Function/Subroutine Documentation 💖

Here's the full signature, no cap — types, order, and all:

subroutine dswap (integer n, double precision, dimension(*) dx, integer
    incx, double precision, dimension(*) dy, integer incy)

DSWAP

✨ Purpose ✨

DSWAP interchanges two vectors. It uses unrolled loops for increments equal to 1. Lowkey obsessed with a clean swap, fr fr. 🔁

🎀 Parameters 🎀

  • N — N is INTEGER; number of elements in input vector(s). Basically how many things we're swapping, periodt. 💫
  • DX — DX is DOUBLE PRECISION array, dimension ( 1 + ( N - 1 )*abs( INCX ) ). The first vector's storage, bestie. 🦋
  • INCX — INCX is INTEGER; storage spacing between elements of DX. Think stride energy. 🌈
  • DY — DY is DOUBLE PRECISION array, dimension ( 1 + ( N - 1 )*abs( INCY ) ). The second vector's storage. 🍓
  • INCY — INCY is INTEGER; storage spacing between elements of DY. Another stride, another slay. 👑

That's the whole page, bestie! Cute footer sign-off: LAPACK Version 3.12.0 BLAS/SRC/dswap.f(3) — and the footer didn't list a date, so we're keeping it mysterious, periodt. 💖✨
