SCOPY(3)

💖 SCOPY(3) — Library Functions Manual 💖

okay bestie, so this one lives in the Library Functions Manual and it's the glow-up story of scopy.f, straight out of the <pink>LAPACK</pink> world. Buckle up, she's short but she's iconic 🎀

🌸 NAME 🌸

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

like... that's literally her whole address, no cap 💅

✨ SYNOPSIS ✨

Functions/Subroutines

subroutine SCOPY (n, sx, incx, sy, incy)

SCOPY — that's her, that's the whole name 🫶

---

🦋 Function/Subroutine Documentation 🦋

subroutine SCOPY (integer n, real, dimension(*) sx, integer incx, real,
    dimension(*) sy, integer incy)

SCOPY 👑

Purpose:

!>
!>    SCOPY copies a vector, x, to a vector, y.
!>    uses unrolled loops for increments equal to 1.
!>

so like, real talk: she copies vector x into vector y, okay? and the moment an increment equals 1 she goes full main-character and uses unrolled loops — she's not doing extra laps for nobody, periodt 🔥

Parameters

• N — N is INTEGER. it's the number of elements in the input vector(s), like how many besties are coming to the party 🎀
• SX — SX is REAL array, dimension ( 1 + ( N - 1 )*abs( INCX ) ) — this is the source, the origin story 💜
• INCX — INCX is INTEGER, the storage spacing between elements of SX — aka how far apart the SX girlies are standing 🦋
• INCY — wait, hold on, keep reading 👇
• SY — SY is REAL array, dimension ( 1 + ( N - 1 )*abs( INCY ) ) — the destination, where the copies land, slay ✨
• INCY — INCY is INTEGER, the storage spacing between elements of SY — same deal as INCX but for the SY side, iykyk 💅

(lol yes the original lists INCX before SY, we're keeping her order exactly, no notes 🙈)

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

okay so she's literally been around since 3/11/78 (jack dongarra, linpack, icon behavior), and then got a little refresh on 12/3/93 where the array(1) declarations were changed to array(*) — a subtle glow-up but we noticed 🌟
