SRC/izmax1.f(3)

okay bestie, welcome to a page from the Library Functions Manual — we're talking about SRC/izmax1.f, and it's giving iconic Level 1 BLAS energy, no cap 💅✨

💖 NAME 💖

SRC/izmax1.f — that's the name, short and slay. periodt.

✨ SYNOPSIS ✨

🧚 Functions/Subroutines 🧚

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

🦋 Function/Subroutine Documentation 🦋

okay so here's the full signature, character for character, bestie:

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

and the whole vibe is: IZMAX1 finds the index of the first vector element of maximum absolute value. 💖

🌸 Purpose 🌸

the purpose is literally IZMAX1 finds the index of the first vector element of maximum absolute value. 🫶

it's Based on IZAMAX from Level 1 BLAS. and the little glow-up is The change is to use the 'genuine' absolute value. so yes, bestie, we're using the genuine article here 🔥

🎀 Parameters 🎀

• N — N is INTEGER. it's The number of elements in the vector ZX. simple, iconic, necessary 👑
• ZX — ZX is COMPLEX*16 array, dimension (N). it's The vector ZX. The IZMAX1 function returns the index of its first element of maximum absolute value. main character vector energy fr fr 🦋
• INCX — INCX is INTEGER. it's The spacing between successive values of ZX. and the rule is INCX >= 1. no zero-step nonsense, okay? 💀
