🌸 NAME 🌸

so this page is literally about /home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/BLAS/SRC/izamax.f — that's the file, bestie, that's the whole name, it's giving full-path realness ✨ (and yes, it's izamax.f(3), from the Library Functions Manual, in case the vibe check needed paperwork 💅)

🦋 SYNOPSIS 🦋

okay so here's the family tree of what lives in this file — the Functions/Subroutines situation:

integer function IZAMAX (n, zx, incx)
    IZAMAX

that's it, that's the icon 👑

🎀 Function/Subroutine Documentation 🎀

⭐ the full signature, no cap ⭐

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

IZAMAX

she's serving lowercase integer function, she's serving complex*16, she's serving dimension(*) — main character energy fr fr 🫶

💖 Purpose 💖

!> !> IZAMAX finds the index of the first element having maximum |Re(.)| + |Im(.)| !>

so like — she goes through your complex vector and finds the index of the first element whose |Re(.)| + |Im(.)| is the biggest. the first one, bestie. ties go to whoever showed up first, no queue-jumping 🧚

🌈 Parameters 🌈

• N

!> N is INTEGER !> number of elements in input vector(s) !>

lowkey just how many things are in your vector(s). that's the count 💫

• ZX

!> ZX is COMPLEX*16 array, dimension ( 1 + ( N - 1 )*abs( INCX ) ) !>

the array itself, COMPLEX*16, and the dimension is exactly ( 1 + ( N - 1 )*abs( INCX ) ) — memorize it, don't freestyle it 🙈

• INCX

!> INCX is INTEGER !> storage spacing between elements of ZX !>

the stride, the gap between the elements you're actually touching — the storage spacing, iykyk ✨

!> !> jack dongarra, 1/15/85. !> modified 3/93 to return if incx .le. 0. !> modified 12/3/93, array(1) declarations changed to array(*) !>

the lore is real: jack dongarra, 1/15/85. — then modified 3/93 to return if incx .le. 0. — then modified 12/3/93, array(1) declarations changed to array(*). a whole historical timeline in three lines, honestly iconic 🌸

ngl the one thing to remember: IZAMAX = first index with max |Re(.)| + |Im(.)|, and incx .le. 0 makes it return. that's the whole tea ☕
