💅 BLAS/SRC/ccopy.f(3)

ok so this is a page from the Library Functions Manual — yes bestie, we're in the Fortran BLAS archives and it's honestly iconic in here 🎀

---

✨ NAME ✨

BLAS/SRC/ccopy.f — the file, the moment, the legend 💫

---

🦋 SYNOPSIS 🦋

Functions/Subroutines

subroutine ccopy (n, cx, incx, cy, incy)
    CCOPY

---

🌸 Function/Subroutine Documentation 🌸

subroutine ccopy (integer n, complex, dimension(*) cx, integer incx,
    complex, dimension(*) cy, integer incy)

CCOPY — she's literally right there in the name, no cap 💅

🎀 Purpose 🎀

!> !> CCOPY copies a vector x to a vector y. !>

that's it. that's the whole job. copy x into y. main character energy, zero drama, she ate and left no crumbs 🍓

🧚 Parameters 🧚

• N

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

how many elements we're working with in the input vector(s) — the headcount of the whole operation fr fr 💖

• CX

!> CX is COMPLEX array, dimension ( 1 + ( N - 1 )*abs( INCX ) )

the source, the origin, the blueprint — it's a COMPLEX array, and yes the dimension formula is exactly ( 1 + ( N - 1 )*abs( INCX ) ), memorize it bestie ✨

• INCX

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

the storage spacing between elements of CX — basically the stride, the lil gap between your faves 🦋

• CY

!> CY is COMPLEX array, dimension ( 1 + ( N - 1 )*abs( INCY ) )

the destination 💫 also a COMPLEX array, dimension ( 1 + ( N - 1 )*abs( INCY ) ) — note it's INCY in this one, don't mix them up 🙈

• INCY

!> INCY is INTEGER !> storage spacing between elements of CY

the storage spacing between elements of CY. matching stride energy, but for the destination 👑

💜 Further Details 💜

!> !> jack dongarra, linpack, 3/11/78. !> modified 12/3/93, array(1) declarations changed to array(*) !>

so the lore is: jack dongarra, linpack, 3/11/78 — historical. and then modified 12/3/93 where the array(1) declarations got changed to array(*) 🔥 glow-up of the decade honestly.

---

lowkey the entire takeaway is: CCOPY copies vector x to vector y, with N elements, spaced INCX apart in CX and INCY apart in CY. that's the vibe check and she passed 😭💖

mwah 💋 that's the page — brought to you by LAPACK, Version 3.12.0, filed under BLAS/SRC/ccopy.f(3). go copy some vectors bestie, slay ✨🎀
