ZCOPY(3)

📦 version 3.12.0, in opensuse-leap 16.0

🌸 zcopy(3) — from the Library Functions Manual, bestie 💅

Okay so picture this: you're deep in /home/abui...SRC/zcopy.f(3) territory, and honestly? It's giving ✨ linear algebra ✨. This is the zcopy page, and yes it's the Fortran BLAS one, not whatever else you were thinking. Sit down, hydrate, let's go 🫶

🎀 NAME

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/BLAS/SRC/zcopy.f

That's the whole NAME, bestie — it's literally just the path to the source file. No cap, that's it. Iconic in a "the manpage gave up" way 💀

✨ SYNOPSIS

Functions/Subroutines

subroutine ZCOPY (n, zx, incx, zy, incy)
    ZCOPY

🦋 Function/Subroutine Documentation

subroutine ZCOPY (integer n, complex*16, dimension(*) zx, integer incx,
    complex*16, dimension(*) zy, integer incy)

ZCOPY

💖 Purpose:

!>
!>    ZCOPY copies a vector, x, to a vector, y.
!>

Lowkey that's the entire personality. It copies. A vector. To another vector. Slay 🎀

💜 Parameters

  • N — N is INTEGER. Number of elements in your input vector(s), so like, how many things you're actually moving. !>
  • ZX — ZX is COMPLEX*16 array, dimension ( 1 + ( N - 1 )*abs( INCX ) ). This is the source situation, the vector we're copying from. !>
  • INCX — INCX is INTEGER. The storage spacing between elements of ZX, aka how far apart your values are chillin'. !>
  • ZY — ZY is COMPLEX*16 array, dimension ( 1 + ( N - 1 )*abs( INCY ) ). The destination — where the copies land. !>
  • INCY — INCY is INTEGER. The storage spacing between elements of ZY. Its own spacing, its own vibe, don't confuse it with INCX fr fr. !>

!>     modified 12/3/93, array(1) declarations changed to array(*)

So yes, jack dongarra, linpack, dated 4/11/78, and then modified 12/3/93 when the array(1) declarations got changed to array(*). History, honestly 👑

Heads up bestie: incx and incy are independently set — the source spacing and destination spacing are separate things. The page tells you the array dimensions are ( 1 + ( N - 1 )*abs( INCX ) ) and ( 1 + ( N - 1 )*abs( INCY ) ), so plan accordingly ✨

Signing off with the footer deets, as promised: this whole thing is LAPACK, Version 3.12.0, and it lives at /home/abui...SRC/zcopy.f(3). Bye bestie, go copy some vectors 💖🦋🌸
