SAXPY(3)

💖 NAME 💖

okay bestie, this page lives in the Library Functions Manual and is filed under saxpy.f(3). The NAME section is literally this exact source path, and I am not touching one character of it:

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

🌸 SYNOPSIS 🌸

🧚 Functions/Subroutines

subroutine SAXPY (n, sa, sx, incx, sy, incy)

Name tag, very demure: SAXPY. 💅

---

✨ Function/Subroutine Documentation ✨

🫶 subroutine SAXPY (integer n, real sa, real, dimension() sx, integer incx, real, dimension() sy, integer incy)

It's SAXPY, bestie. That's the name. 🎀

🎀 Purpose

SAXPY is out here doing the iconic BLAS thing: constant times a vector plus a vector. And the source is very clear that it uses unrolled loops for increments equal to one. That's the whole purpose, periodt. ✨

reminder from the source: the unrolled-loops behavior is for increments equal to one, exactly as stated. no cap. 🔥

🌈 Parameters

• N — N is INTEGER; it's the number of elements in input vector(s). 🍓
• SA — SA is REAL; on entry, SA specifies the scalar alpha. 💖
• SX — SX is REAL array, dimension ( 1 + ( N - 1 )*abs( INCX ) ). 🦋
• INCX — INCX is INTEGER; storage spacing between elements of SX. 💫
• SY — SY is REAL array, dimension ( 1 + ( N - 1 )*abs( INCY ) ). 🌸
• INCY — INCY is INTEGER; storage spacing between elements of SY. 🌈
