SRC/zrscl.f(3)

💅 SRC/zrscl.f — the manual page, bestie ✨

okay so this is SRC/zrscl.f(3) from the Library Functions Manual — manual name folded in right at the top, you’re welcome. It’s all about the zrscl subroutine, and we’re gonna get into it. 🫶

🌸 NAME 🌸

SRC/zrscl.f

📜 SYNOPSIS 📜

✨ Functions/Subroutines ✨

• subroutine zrscl (n, a, x, incx) — ZDRSCL multiplies a vector by the reciprocal of a real scalar. yes bestie, that’s exactly what it says — keep reading, the purpose section has more. 💅

🧚 Function/Subroutine Documentation 🧚

💖 subroutine zrscl 💖

subroutine zrscl (integer n, complex*16 a, complex*16, dimension( * ) x,
    integer incx)

ZDRSCL multiplies a vector by the reciprocal of a real scalar.

🌟 Purpose 🌟

ZRSCL multiplies an n-element complex vector x by the complex scalar 1/a. This is done without overflow or underflow as long as the final result x/a does not overflow or underflow. no cap, that’s the whole point. ✨

heads up bestie: the synopsis says ZDRSCL and the purpose says ZRSCL — that’s exactly how the original is giving it. I’m not editing either one. 💅

🌸 Parameters 🌸

• N — N is INTEGER. The number of components of the vector x. 💖
• A — A is COMPLEX*16. The scalar a which is used to divide each component of x. A must not be 0, or the subroutine will divide by zero. like, do not do that, bestie. 😭
• X — X is COMPLEX*16 array, dimension (1+(N-1)*abs(INCX)). The n-element vector x. 🦋
• INCX — INCX is INTEGER. The increment between successive values of the vector SX. For > 0: SX(1) = X(1) and SX(1+(i-1)*INCX) = x(i), 1< i<= n. 👑

okay bestie, that’s the whole tea: LAPACK, Version 3.12.0, from source file SRC/zrscl.f(3). The footer didn’t give a separate date, so I’m not making one up — periodt. 💖✨
