SRC/drscl.f(3)

💅 SRC/drscl.f 💅

okay bestie, welcome to the Library Functions Manual page for SRC/drscl.f — this is the whole vibe, and no cap, it's a little routine icon. 🫶

🌸 NAME 🌸

SRC/drscl.f — that's literally the name, bestie.

✨ SYNOPSIS ✨

🧚 Functions/Subroutines 🧚

• subroutine drscl (n, sa, sx, incx) — DRSCL multiplies a vector by the reciprocal of a real scalar.

📚 Function/Subroutine Documentation 📚

subroutine drscl (integer n, double precision sa, double precision, dimension( * ) sx, integer incx)

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

🎯 Purpose: 🎯

okay so the actual purpose, fr fr: DRSCL multiplies an n-element real vector x by the real scalar 1/a. This is done without overflow or underflow as long as the final result x/a does not overflow or underflow. 💖

🧮 Parameters

• N — N is INTEGER. It's the number of components of the vector x. slay, simple.
• SA — SA is DOUBLE PRECISION. This is the scalar a which is used to divide each component of x. 🚨 SA must be >= 0, or the subroutine will divide by zero. not me warning you, it's literally in the docs.
• SX — SX is DOUBLE PRECISION array, dimension (1+(N-1)*abs(INCX)). This is the n-element vector x. the way that dimension formula ate, iykyk.
• INCX — INCX is INTEGER. This is the increment between successive values of the vector SX. The exact condition is:

> 0:  SX(1) = X(1) and SX(1+(i-1)*INCX) = x(i),     1< i<= n
