✨ BLAS/SRC/csrot.f(3) ✨

okay bestie, welcome to the LAPACK corner of the manual, specifically BLAS/SRC/csrot.f 🎀 — yes, the file name is the whole vibe, it's giving "I live in the BLAS directory and I'm thriving."

🌸 NAME 🌸

BLAS/SRC/csrot.f — the main character file 💅

🦋 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. 🌸

🌟 Parameters 🌟

  • N — N is INTEGER
    • On entry, N specifies the order of the vectors cx and cy.
    • N must be at least zero. 🫶
  • 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 is overwritten by the updated vector cx. 💀 yes bestie, it gets replaced, that's just the way it is.
  • INCX — INCX is INTEGER
    • On entry, INCX specifies the increment for the elements of CX. INCX must not be zero. 🚨
  • 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. 😭 gone but iconic.
  • INCY — INCY is INTEGER
    • On entry, INCY specifies the increment for the elements of CY. INCY must not be zero. 🚨
  • C — C is REAL
    • On entry, C specifies the cosine, cos. 🌸
  • S — S is REAL
    • On entry, S specifies the sine, sin. 🦋
