💅 NAME 💅

ok so bestie, this page is all about /home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/BLAS/SRC/sdsdot.f

it's giving "library functions manual" energy, the header said /home/abui...C/sdsdot.f(3) and honestly? iconic. it lives in the LAPACK Version 3.12.0 cinematic universe 🎀

✨ SYNOPSIS ✨

Functions/Subroutines

real function SDSDOT (n, sb, sx, incx, sy, incy)

SDSDOT — that's the whole name, no notes 💅

---

🦋 Function/Subroutine Documentation 🦋

real function SDSDOT (integer n, real sb, real, dimension(*) sx, integer incx,
    real, dimension(*) sy, integer incy)

SDSDOT. the main character fr.

🌸 Purpose:

!>
!>   Compute the inner product of two vectors with extended
!>   precision accumulation.
!>
!>   Returns S.P. result with dot product accumulated in D.P.
!>   SDSDOT = SB + sum for I = 0 to N-1 of SX(LX+I*INCX)*SY(LY+I*INCY),
!>   where LX = 1 if INCX .GE. 0, else LX = 1+(1-N)*INCX, and LY is
!>   defined in a similar way using INCY.
!>

like, it does the dot product but accumulates in double precision and hands you back a single precision result — no cap, that's the whole flex ✨

🌈 Parameters 🌈

• N — N is INTEGER, the number of elements in the input vector(s). lowkey important.

!>          N is INTEGER
!>          number of elements in input vector(s)
!>

• SB — SB is REAL, the single precision scalar you're adding onto the inner product. yes she gets added. periodt.

!>          SB is REAL
!>          single precision scalar to be added to inner product
!>

• SX — SX is REAL array, dimension ( 1 + ( N - 1 )*abs( INCX ) ), a single precision vector with N elements 🍓

!>          SX is REAL array, dimension ( 1 + ( N - 1 )*abs( INCX ) )
!>          single precision vector with N elements
!>

• INCX — INCX is INTEGER, the storage spacing between elements of SX. the stride, bestie 💫

!>          INCX is INTEGER
!>          storage spacing between elements of SX
!>

• SY — SY is REAL array, dimension ( 1 + ( N - 1 )*abs( INCX ) ), a single precision vector with N elements. (yes, the original says INCX in this dimension expression, not INCY — we're reporting the tea exactly as served, no edits, not my business 🙈)

!>          SY is REAL array, dimension ( 1 + ( N - 1 )*abs( INCX ) )
!>          single precision vector with N elements
!>

• INCY — INCY is INTEGER, the storage spacing between elements of SY. the other stride, the second half of the duo 🫶

!>          INCY is INTEGER
!>          storage spacing between elements of SY
!>
