BLAS/SRC/zdotc.f(3)

💖 NAME

Okay so this page is BLAS/SRC/zdotc.f(3), and it's living in the Library Functions Manual — manual name folded in near the top, as requested, bestie. The actual NAME is BLAS/SRC/zdotc.f. That's the whole name section. Iconic, short, slay.

✨ SYNOPSIS

🌸 Functions/Subroutines

• complex *16 function zdotc (n, zx, incx, zy, incy) — ZDOTC

🦋 Function/Subroutine Documentation

Here's the full signature, and I'm keeping it exactly as it appears because we do not play with code:

complex*16 function zdotc (integer n, complex*16, dimension(*) zx, integer incx, complex*16, dimension(*) zy, integer incy)

ZDOTC — that's the function, periodt.

🎀 Purpose:

The original Doxygen block says this, word for word:

!>
!> ZDOTC forms the dot product of two complex vectors
!>      ZDOTC = X^H * Y
!>
!>

So yes: ZDOTC forms the dot product of two complex vectors, and the formula is ZDOTC = X^H * Y. It's giving math but make it BLAS 💅.

🍓 Parameters

• N — N is INTEGER; it's the number of elements in input vector(s).
• ZX — ZX is COMPLEX*16 array, dimension ( 1 + ( N - 1 )*abs( INCX ) ).
• INCX — INCX is INTEGER; it's the storage spacing between elements of ZX.
• ZY — ZY is COMPLEX*16 array, dimension ( 1 + ( N - 1 )*abs( INCY ) ).
• INCY — INCY is INTEGER; it's the storage spacing between elements of ZY.

So: jack dongarra, 3/11/78. Then modified 12/3/93, array(1) declarations changed to array(*). A little historical glow-up, we love to see it.
