✨ SYNOPSIS ✨

🧚 Functions/Subroutines 🧚

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

💖 Function/Subroutine Documentation 💖

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

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

🌸 Purpose 🌸

Okay so picture an n-element real vector x. SRSCL multiplies it by the real scalar 1/a, and it does this without overflow or underflow as long as the final result x/a does not overflow or underflow. That's the whole vibe. ✨

🎀 Parameters 🎀

  • N — N is INTEGER; it's the number of components of the vector x.
  • SA — SA is REAL; 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. Respect the boundary, bestie. 💀
  • SX — SX is a REAL array, dimension (1+(N-1)*abs(INCX)); it's the n-element vector x. 👑
  • INCX — INCX is INTEGER; it's the increment between successive values of the vector SX. Specifically: > 0: SX(1) = X(1) and SX(1+(i-1)*INCX) = x(i), 1< i<= n. Slay, indexing. 🌀
