BLAS/SRC/csscal.f(3)

✨ NAME ✨

BLAS/SRC/csscal.f — bestie, this is the whole file, and it's about to scale your whole complex vector by a real number 💖

---

🌸 SYNOPSIS 🌸

Functions/Subroutines

subroutine csscal (n, sa, cx, incx)
    CSSCAL

---

🎀 Function/Subroutine Documentation 🎀

subroutine csscal (integer n, real sa, complex, dimension(*) cx, integer incx)
    CSSCAL

💅 Purpose:

CSSCAL scales a complex vector by a real constant. That's it, that's the whole job, and she does it flawlessly, periodt ✨

🦋 Parameters

• N — ok so, N is INTEGER, and it's the number of elements in input vector(s). That's the headcount, the guest list, how many of them you brought 🌸
• SA — SA is REAL. On entry, SA specifies the scalar alpha. So like, this is the real number doing the scaling — the main character of the multiplication, lowkey 👑
• CX — CX is COMPLEX array, dimension ( 1 + ( N - 1 )*abs( INCX ) ). Yes bestie, the dimension expression is literally that, don't @ me 🙈
• INCX — INCX is INTEGER, and it's the storage spacing between elements of CX. It's the stride, the little gap between your elements, the way you walk through the array 🚶‍♀️

Not the historical receipts being right there in the source 😭 three eras of edits and every single one of them preserved, we love a documented glow-up 🫶
