SASUM(3)

🎀 NAME 🎀

ok so bestie, this page is literally about /home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/BLAS/SRC/sasum.f — like, that's the actual file, that whole entire path, and it's the LAPACK source file for SASUM. iykyk 💅

✨ SYNOPSIS ✨

Functions/Subroutines

• real function SASUM (n, sx, incx) — yes that's the whole vibe, she's a real function called SASUM, and she takes n, sx, incx. that's it, that's the girl 🫶
  • SASUM

💖 Function/Subroutine Documentation 💖

real function SASUM (integer n, real, dimension(*) sx, integer incx)

SASUM — the main character herself 👑

🌸 Purpose: 🌸

!>
!>    SASUM takes the sum of the absolute values.
!>    uses unrolled loops for increment equal to one.
!>

ok so real talk: SASUM takes the sum of the absolute values. that's the whole job, no cap. and lowkey iconic detail — it uses unrolled loops when the increment is equal to one 🔥 (yes, she's optimizing, she's that girl 💅).

🦋 Parameters 🦋

• N — N is INTEGER, and it's the number of elements in the input vector(s). that's the count, bestie, keep track of it fr fr.

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

• SX — SX is a REAL array, and her dimension is exactly ( 1 + ( N - 1 )*abs( INCX ) ). yes copy it exactly like that, bestie, don't be out here guessing the size 🙈.

!>          SX is REAL array, dimension ( 1 + ( N - 1 )*abs( INCX ) )
!>

• INCX — INCX is INTEGER, and it's the storage spacing between elements of SX. so like, the stride energy 🌈.

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

ok so the lore 📖 — jack dongarra, linpack, 3/11/78. then it got modified 3/93 to return if incx .le. 0. and then modified 12/3/93, array(1) declarations changed to array(*). the character development is real 😭💖

ngl bestie, everything above is straight from the LAPACK docs — Version 3.12.0, and the source file is /home/abui...SRC/sasum.f(3). slay, go sum some absolute values 💅✨🍓
