okay so bestie, welcome to the Library Functions Manual page for /home/abui...C/dzasum.f(3) 💅✨

🌸 NAME 🌸

This is the manual page for the BLAS source file:

✨ SYNOPSIS ✨

🦋 Functions/Subroutines 🦋

double precision function DZASUM (n, zx, incx)
    DZASUM

---

🦋 FUNCTION/SUBROUTINE DOCUMENTATION 🦋

DZASUM is the main character here. The signature in the docs is:

double precision function DZASUM (integer n, complex*16, dimension(*) zx,
    integer incx)

DZASUM

🌸 Purpose 🌸

The source’s purpose block says, literally:

!>
!>    DZASUM takes the sum of the (|Re(.)| + |Im(.)|)'s of a complex vector and
!>    returns a double precision result.
!>

Translation for the group chat: it sums up the absolute real part plus the absolute imaginary part across a complex vector, and returns a double precision result. literally that’s the whole vibe 💖

🎀 PARAMETERS 🎀

• N — N is INTEGER; it’s the number of elements in input vector(s). periodt.
• ZX — ZX is COMPLEX*16 array, dimension ( 1 + ( N - 1 )*abs( INCX ) ). iconic array energy.
• INCX — INCX is INTEGER; storage spacing between elements of ZX. spacing details, slay.
