🦋 DZSUM1(3) — Library Functions Manual 🦋

okay bestie, welcome to the manual page for DZSUM1(3) — manual name right there in the title, and it lives under Library Functions Manual. The source file is the whole mood:

💖 NAME 💖

• /home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/SRC/dzsum1.f — literally the name section, no extra lore. 🎀

✨ SYNOPSIS ✨

Functions/Subroutines

double precision function DZSUM1 (n, cx, incx)

DZSUM1 forms the 1-norm of the complex vector using the true absolute value. Slay.

🌸 Function/Subroutine Documentation 🌸

double precision function DZSUM1

double precision function DZSUM1 (integer n, complex*16, dimension( * ) cx,
    integer incx)

DZSUM1 forms the 1-norm of the complex vector using the true absolute value. Yes, it said it twice — iconic consistency.

🍓 Purpose 🍓

Here's the purpose block, copied exactly so no vibes get lost:

!>
!> DZSUM1 takes the sum of the absolute values of a complex
!> vector and returns a double precision result.
!>
!> Based on DZASUM from the Level 1 BLAS.
!> The change is to use the 'genuine' absolute value.
!>

So: sum the absolute values of a complex vector, return a double precision result, and it's based on DZASUM from the Level 1 BLAS. The plot twist is using the 'genuine' absolute value. 💅

🌈 Parameters 🌈

• N — N is INTEGER. It's the number of elements in the vector CX. ✨
• CX — CX is COMPLEX*16 array, dimension (N). This is the vector whose elements will be summed. 💜
• INCX — INCX is INTEGER. It's the spacing between successive values of CX. INCX > 0. Important! 🫶
