CAXPY(3)

💅 CAXPY(3) — like, the manual page, bestie

okay so this is a page from the Library Functions Manual (that's the manual name, we're folding it in, you're welcome ✨) and it's all about caxpy.f — and yes the full path is a whole vibe:

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

that's the NAME section, that's literally it, that's the name 🎀

✨ SYNOPSIS ✨

Functions/Subroutines

• subroutine CAXPY (n, ca, cx, incx, cy, incy) — that's our girl. that's the whole subroutine. CAXPY.

---

🦋 Function/Subroutine Documentation 🦋

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

CAXPY 💖

🎀 Purpose 🎀

!> !> CAXPY constant times a vector plus a vector. !>

like, it does constant times vector plus vector. that's the entire personality and honestly? iconic. it ate. 🔥

🌸 Parameters 🌸

• N

!> N is INTEGER !> number of elements in input vector(s) so N is an INTEGER, and it's how many elements live in your input vector(s). no cap 🫶

• CA

!> CA is COMPLEX !> On entry, CA specifies the scalar alpha. CA is COMPLEX, and on entry it's the scalar alpha. that's the "constant" in "constant times a vector", bestie 💅

• CX

!> CX is COMPLEX array, dimension ( 1 + ( N - 1 )*abs( INCX ) ) CX is a COMPLEX array and its dimension is ( 1 + ( N - 1 )*abs( INCX ) ). yes, exactly that. don't @ me, that's literally what it says ✨

• INCX

!> INCX is INTEGER !> storage spacing between elements of CX INCX is INTEGER and it's the storage spacing between elements of CX. it's giving stride energy 👑

• CY

!> CY is COMPLEX array, dimension ( 1 + ( N - 1 )*abs( INCY ) ) CY is a COMPLEX array, dimension ( 1 + ( N - 1 )*abs( INCY ) ). same deal, different letter 🍓

• INCY

!> INCY is INTEGER !> storage spacing between elements of CY INCY is INTEGER, storage spacing between elements of CY. the way it mirrors INCX… symmetry slay 🌈

so jack dongarra, linpack, 3/11/78. — that's the origin story. and then modified 12/3/93, array(1) declarations changed to array(*) — the glow-up. we love a documented evolution 😭✨
