CSCAL(3)

💅 CSCAL(3) — like, the complex scalar multiply era ✨

okay so real talk: this page lives in the Library Functions Manual, and the file it's literally from is /home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/BLAS/SRC/cscal.f — yes that's the whole path, no I'm not abbreviating it, she's long but she's iconic 🎀

✨ NAME ✨

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/BLAS/SRC/cscal.f — bestie this is the file, that's the whole name section, we move 🦋

🌸 SYNOPSIS 🌸

Functions/Subroutines

subroutine CSCAL (n, ca, cx, incx)
    CSCAL

👑 Function/Subroutine Documentation 👑

subroutine CSCAL (integer n, complex ca, complex, dimension(*) cx, integer
    incx)

CSCAL 🫶

💖 Purpose:

!>
!>    CSCAL scales a vector by a constant.
!>

like literally that's the whole vibe — it scales a vector by a constant. no cap, that's it, that's the function 💅

🦋 Parameters 🦋

• N — N is INTEGER, and it's the number of elements in the input vector(s). that's the headcount bestie, know your guest list ✨
• CA — CA is COMPLEX. on entry, CA specifies the scalar alpha. this is the constant doing the scaling, the main character of the whole operation 👑
• CX — CX is COMPLEX array, dimension ( 1 + ( N - 1 )*abs( INCX ) ). yes the dimension expression is exactly that, don't come for me, I'm just the messenger 🎀
• INCX — INCX is INTEGER, the storage spacing between elements of CX. how far apart the elements are chilling from each other, basically 🌈

so she's got lore — jack dongarra, linpack, back on 3/11/78. then modified 3/93 to return if incx .le. 0, and modified 12/3/93 where the array(1) declarations changed to array(*). a whole glow-up journey over like fifteen years, we love a survivor 😭💖

okay that's the page!! 🎀 and for the cute sign-off: this whole thing is LAPACK, Version 3.12.0, from /home/abui...SRC/cscal.f(3) — go forth and scale those vectors, bestie, incx .le. 0 and all 💅🫶🌸
