🌸 NAME 🌸

Okay bestie, meet imax1(3) — the manual page name is literally imax1(3), and the name line is imax1: argmax_i | x_i | (in LAPACK). No cap, that's the whole name. 💖

🌈 SYNOPSIS 🌈

🛠️ Functions 🛠️

  • integer function icmax1 (n, cx, incx) — ICMAX1 finds the index of the first vector element of maximum absolute value. ✨
  • integer function izmax1 (n, zx, incx) — IZMAX1 finds the index of the first vector element of maximum absolute value. 💜

💅 Detailed Description 💅

This is the detailed-description zone, and the source has no extra prose here — it just slides right into the function documentation below. 🫶

🧚 Function Documentation 🧚

💖 icmax1 💖

Here's the full signature, exactly as written:

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

🎯 Purpose 🎯

  • ICMAX1 finds the index of the first vector element of maximum absolute value. 👑
  • It's based on ICAMAX from Level 1 BLAS.
  • The change is to use the 'genuine' absolute value. No fake-abs energy here. 💅

🧸 Parameters 🧸

  • N — N is INTEGER; it's the number of elements in the vector CX. ✨
  • CX — CX is COMPLEX array, dimension (N); this is the vector CX, and the ICMAX1 function returns the index of its first element of maximum absolute value. 💖
  • INCX — INCX is INTEGER; this is the spacing between successive values of CX, and INCX >= 1. 🫶

💜 izmax1 💜

Here's the full signature, exactly as written:

integer function izmax1 (integer n, complex*16, dimension(*) zx, integer incx)

🎯 Purpose 🎯

  • IZMAX1 finds the index of the first vector element of maximum absolute value. 👑
  • It's based on IZAMAX from Level 1 BLAS.
  • The change is to use the 'genuine' absolute value. Literally the same iconic abs upgrade. 💅

🧸 Parameters 🧸

  • N — N is INTEGER; it's the number of elements in the vector ZX. ✨
  • ZX — ZX is COMPLEX*16 array, dimension (N); this is the vector ZX, and the IZMAX1 function returns the index of its first element of maximum absolute value. 💖
  • INCX — INCX is INTEGER; this is the spacing between successive values of ZX, and INCX >= 1. 🫶
