✨ SYNOPSIS ✨

🌸 Functions/Subroutines 🌸

• integer function IDAMAX (n, dx, incx) — literally IDAMAX, that's it, that's the whole thing 🎀

---

🦋 Function/Subroutine Documentation 🦋

integer function IDAMAX (integer n, double precision, dimension(*) dx,
    integer incx)

ok so this is IDAMAX again (the docs just love repeating themselves, iykyk) 👑

🎯 Purpose:

!>
!>    IDAMAX finds the index of the first element having maximum absolute value.
!>

fr fr, that's the whole job: it finds the index of the first element that has the maximum absolute value. bestie said "i want numbers, not just the biggest one" and honestly, iconic. 🔥

💜 Parameters

• N — !> N is INTEGER, the number of elements in the input vector(s). like, how many things are we even looking at 🫶
• DX — !> DX is DOUBLE PRECISION array, dimension ( 1 + ( N - 1 )*abs( INCX ) ). that dimension formula is doing the absolute most but it's correct, don't @ me 💀
• INCX — !> INCX is INTEGER, the storage spacing between elements of DX. so like, do you want every element or every third one, your call ✨

ok so this is like. the lore. 👑

• jack dongarra, linpack, 3/11/78. — the original era, nickname and all, we love a legend
• modified 3/93 to return if incx .le. 0. — early-90s glow-up: now it bails out when incx is .le. 0
• modified 12/3/93, array(1) declarations changed to array(*) — december '93 upgrade, array(1) got switched to array(*)
