🌸 SRC/icmax1.f 🌸

okay bestie so this is a man page for SRC/icmax1.f — it's a library functions manual page, and it's basically the whole vibe of "which element of my complex vector is the absolute biggest?" 💅 lowkey iconic.

✨ SYNOPSIS ✨

🫶 Functions/Subroutines

  • integer function icmax1 (n, cx, incx) — ICMAX1 finds the index of the first vector element of maximum absolute value. slay.

🧚 Function/Subroutine Documentation 🧚

integer function icmax1 (integer n, complex, dimension(*) cx, integer incx)

ICMAX1 finds the index of the first vector element of maximum absolute value. that's it, that's the whole job, and it ate. ✨

🎀 Purpose 🎀

!>
!> ICMAX1 finds the index of the first vector element of maximum absolute value.
!>
!> Based on ICAMAX from Level 1 BLAS.
!> The change is to use the 'genuine' absolute value.
!>

so yeah — it's giving ICAMAX energy (shoutout Level 1 BLAS, the blueprint 💖), but the glow-up is that it uses the genuine absolute value. no cap, that's the whole difference. 🦋

🌈 Parameters 🌈

  • N — N is INTEGER. it's literally just the number of elements in the vector CX. that's the headcount, bestie. 🍓
!>          N is INTEGER
!>          The number of elements in the vector CX.
!>
  • CX — CX is COMPLEX array, dimension (N). this is the vector CX itself, and the ICMAX1 function returns the index of its first element of maximum absolute value. first one wins — we don't do ties here, we do first 🥇
!>          CX is COMPLEX array, dimension (N)
!>          The vector CX. The ICMAX1 function returns the index of its first
!>          element of maximum absolute value.
!>
  • INCX — INCX is INTEGER. it's the spacing between successive values of CX. and listen: INCX >= 1, periodt. don't come at it with zero or negative, it's not that kind of party. 💀
!>          INCX is INTEGER
!>          The spacing between successive values of CX.  INCX >= 1.

💜 okay that's the whole page! no detail left behind, every flag and parameter accounted for, vibe check passed with flying colors 🌈

LAPACK — Version 3.12.0 — and that's the SRC/icmax1.f(3) sign-off, bestie! mwah 💋
