ZAXPY(3)

💅 NAME 💅

okay so you opened zaxpy.f(3) from the Library Functions Manual — welcome to the group chat, bestie 💖. The actual file this page is about is exactly:

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

---

✨ SYNOPSIS ✨

Functions/Subroutines, periodt. The whole lineup is:

       subroutine ZAXPY (n, za, zx, incx, zy, incy)
           ZAXPY

---

📚 Function/Subroutine Documentation 📚

Main character energy: here’s the full signature, no cap:

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

🎀 Purpose 🎀

The source comments say it plainly:

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

So yeah: ZAXPY constant times a vector plus a vector. It’s giving scalar-times-vector-plus-vector realness, and honestly? Obsessed. 🔥

🌸 Parameters 🌸

• N — INTEGER; number of elements in input vector(s). The count bestie, the whole vibe check. 💖
• ZA — COMPLEX*16. On entry, ZA specifies the scalar alpha. The moment.
• ZX — COMPLEX*16 array, dimension ( 1 + ( N - 1 )*abs( INCX ) ). That’s the first vector, slay.
• INCX — INTEGER; storage spacing between elements of ZX. Basically the stride, bestie.
• ZY — COMPLEX*16 array, dimension ( 1 + ( N - 1 )*abs( INCY ) ). The second vector, also iconic.
• INCY — INTEGER; storage spacing between elements of ZY. Another stride, another vibe.

Not me keeping the dates exact: jack dongarra, 3/11/78. and modified 12/3/93, array(1) declarations changed to array(*) — periodt. 🫶
