CSROT(3)

📦 version 3.12.0, in opensuse-leap 16.0

💅 CSROT(3) — like, the BLAS plane-rotation icon herself 🌀

okay so real talk, this page is csrot.f(3) from the Library Functions Manual, and the file lives at /home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/BLAS/SRC/csrot.f — yes that's the whole path, she's got a long address, main character energy fr fr 🏡✨

✨ NAME ✨

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

that's it. that's the name. it's a whole path, bestie, and we respect it 💖

🌸 SYNOPSIS 🌸

Functions/Subroutines

subroutine CSROT (n, cx, incx, cy, incy, c, s)
    CSROT

🦋 Function/Subroutine Documentation 🦋

subroutine CSROT (integer n, complex, dimension( * ) cx, integer incx,
    complex, dimension( * ) cy, integer incy, real c, real s)

CSROT

🎀 Purpose 🎀

!> !> CSROT applies a plane rotation, where the cos and sin (c and s) are real !> and the vectors cx and cy are complex. !> jack dongarra, linpack, 3/11/78. !>

so like — she rotates things 💫 it's a plane rotation, the c and s (cos and sin) are real, and the vectors cx and cy are complex. iconic combo, no cap. and shoutout to jack dongarra, linpack, 3/11/78 — the original author, we stan a legend 👑

🔥 Parameters 🔥

  • N — N is INTEGER. on entry, N specifies the order of the vectors cx and cy, and it must be at least zero (so no negatives, she's not doing that today 🙅‍♀️).
  • CX — CX is COMPLEX array, dimension at least ( 1 + ( N - 1 )*abs( INCX ) ). before entry, the incremented array CX must contain the n element vector cx. on exit, CX gets overwritten by the updated vector cx — yep, she's mutating in place, that's the vibe 💅.
  • INCX — INCX is INTEGER. on entry, INCX specifies the increment for the elements of CX, and it must not be zero (zero would be a whole mess, don't 👀).
  • CY — CY is COMPLEX array, dimension at least ( 1 + ( N - 1 )*abs( INCY ) ). before entry, the incremented array CY must contain the n element vector cy. on exit, CY is overwritten by the updated vector cy. twin behavior with CX, matching outfits fr fr 🫶.
  • INCY — INCY is INTEGER. on entry, INCY specifies the increment for the elements of CY, and it must not be zero. same rule, same energy ✨.
  • C — C is REAL. on entry, C specifies the cosine, cos. that's her whole job 🍓.
  • S — S is REAL. on entry, S specifies the sine, sin. and that's her whole job 🌈.
