💅 DASUM(3) — the absolute-value glow-up 🎀

ok so bestie, real talk: this page lives at /home/abui...SRC/dasum.f(3) and it's part of the <pink>Library Functions Manual</pink>, which is giving "yes queen, you found the BLAS shelf." the whole thing is literally the man page for /home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/BLAS/SRC/dasum.f — like, that's the file, that's the vibe, and we're gonna walk through it together 🫶

✨ SYNOPSIS ✨

Functions/Subroutines 🌸

double precision function DASUM (n, dx, incx)

DASUM — that's her, that's the function ✨

---

🦋 Function/Subroutine Documentation 🦋

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

DASUM 💖

🎀 Purpose:

!>
!>    DASUM takes the sum of the absolute values.
!>

ok what does she do. she takes the sum of the absolute values. that's it. that's the whole personality no cap 👑

🌈 Parameters

• N — N is INTEGER. literally the number of elements in your input vector(s). the count. the headcount. the guest list 💅

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

• DX — DX is a DOUBLE PRECISION array, with dimension ( 1 + ( N - 1 )*abs( INCX ) ). yes bestie, read that formula, we'll wait 🍓

!>          DX is DOUBLE PRECISION array, dimension ( 1 + ( N - 1 )*abs( INCX ) )
!>

• INCX — INCX is INTEGER, and it's the storage spacing between elements of DX. so like, how far apart the girlies are standing 💀

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

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

so the lore is: jack dongarra, linpack, 3/11/78. — then modified 3/93 to return if incx .le. 0. — then modified 12/3/93, array(1) declarations changed to array(*). history. we stan a documented changelog 📜💖
