💖 SRC/slargv.f(3) 💖

okay so bestie, this is the SRC/slargv.f(3) page from the Library Functions Manual — manual name folded in near the top just like we planned, and the vibe is very “tiny rotation subroutine that ate.” 🫶✨ We're keeping every single detail, so let's go.

✨ NAME ✨

SRC/slargv.f

🌸 SYNOPSIS 🌸

🫶 Functions/Subroutines 🫶

  • subroutine slargv (n, x, incx, y, incy, c, incc) — SLARGV generates a vector of plane rotations with real cosines and real sines. periodt. 💅

🎀 Function/Subroutine Documentation 🎀

   subroutine slargv (integer n, real, dimension( * ) x, integer incx, real,
       dimension( * ) y, integer incy, real, dimension( * ) c, integer incc)

SLARGV generates a vector of plane rotations with real cosines and real sines. yes, it's that girl. 🌈

💖 Purpose 💖

the source comment is literally this, !> markings and all:

!>
!> SLARGV generates a vector of real plane rotations, determined by
!> elements of the real vectors x and y. For i = 1,2,...,n
!>
!>    (  c(i)  s(i) ) ( x(i) ) = ( a(i) )
!>    ( -s(i)  c(i) ) ( y(i) ) = (   0  )
!>

🍓 Parameters 🍓

  • N — N is INTEGER. The number of plane rotations to be generated. 💫
  • X — X is REAL array, dimension (1+(N-1)*INCX). On entry, the vector x. On exit, x(i) is overwritten by a(i), for i = 1,...,n. 🦋
  • INCX — INCX is INTEGER. The increment between elements of X. INCX > 0. ⭐
  • Y — Y is REAL array, dimension (1+(N-1)*INCY). On entry, the vector y. On exit, the sines of the plane rotations. 🌸
  • INCY — INCY is INTEGER. The increment between elements of Y. INCY > 0. 💜
  • C — C is REAL array, dimension (1+(N-1)*INCC). The cosines of the plane rotations. 🎀
  • INCC — INCC is INTEGER. The increment between elements of C. INCC > 0. 💅

k bye bestie, mwah 💋 this page is from LAPACK, Version 3.12.0, and the source/page is SRC/slargv.f(3). the footer didn't give a date line, so I'm not inventing one — no cap, periodt. 🎀✨
