okay bestie, welcome to the Library Functions Manual side of the group chat — this page is all about SRC/csrscl.f, and it’s lowkey iconic. 🫶

✨ NAME ✨

SRC/csrscl.f

🌸 SYNOPSIS 🌸

Functions/Subroutines

• subroutine csrscl (n, sa, sx, incx) — CSRSCL multiplies a vector by the reciprocal of a real scalar. slay. 💅

🦋 Function/Subroutine Documentation 🦋

subroutine csrscl (integer n, real sa, complex, dimension( * ) sx, integer incx)

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

🎀 Purpose: 🎀

okay so CSRSCL multiplies an n-element complex vector x by the real scalar 1/a. The way it does this is specifically so there’s no overflow or underflow — as long as the final result x/a does not overflow or underflow. no cap. ✨

🌸 Parameters 🌸

• N — N is INTEGER. The number of components of the vector x. literally the count, bestie.
• SA — SA is REAL. The scalar a which is used to divide each component of x. SA must be >= 0, or the subroutine will divide by zero. 🚨 so please don’t do that.
• SX — SX is COMPLEX array, dimension (1+(N-1)*abs(INCX)). The n-element vector x. that’s the main character right there.
• INCX — INCX is INTEGER. The increment between successive values of the vector SX. > 0: SX(1) = X(1) and SX(1+(i-1)*INCX) = x(i), 1< i<= n — iykyk. 💫
