💫 BLAS/SRC/srot.f — from the Library Functions Manual ✨

okay so picture this: you're deep in the LAPACK docs, the BLAS/SRC folder specifically, and you find srot.f. that's our girl. she's a Fortran file, she does one thing, and she does it iconically. let's get into it 🎀

🌸 NAME 🌸

BLAS/SRC/srot.f — literally just the file, bestie. that's the whole name. no cap.

✨ SYNOPSIS ✨

🦋 Functions/Subroutines

subroutine srot (n, sx, incx, sy, incy, c, s)

SROT — the main character herself 💅

👑 Function/Subroutine Documentation 👑

subroutine srot (integer n, real, dimension(*) sx, integer incx, real,
    dimension(*) sy, integer incy, real c, real s)

SROT. she's here, she's serving, she rotates planes. 🌀

🧚 Purpose:

applies a plane rotation.

that's it. that's the whole purpose. lowkey elegant, highkey iconic. ✨

💜 Parameters

  • N — N is INTEGER, the number of elements in your input vector(s). like, how many besties are we rotating today 🫶
  • SX — SX is REAL array, dimension ( 1 + ( N - 1 )*abs( INCX ) ). the first vector, living her best life as a REAL array.
  • INCX — INCX is INTEGER, the storage spacing between elements of SX. think of it as how far apart the girls are standing 💃
  • SY — SY is REAL array, dimension ( 1 + ( N - 1 )*abs( INCY ) ). the second vector, also a REAL array, also thriving.
  • INCY — INCY is INTEGER, the storage spacing between elements of SY. same energy as INCX but for the other vector, iykyk 🌈
  • C — C is REAL. that's it, that's the parameter. she's just C 💀
  • S — S is REAL. and this one's just S. no notes. 🙈

so she's vintage — original author credit goes to jack dongarra, linpack, dated 3/11/78, and then she got a lil glow-up on 12/3/93 when the array(1) declarations were changed to array(*). a true makeover moment 💅✨
