DLARTV(3)

🌸 NAME 🌸

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/SRC/dlartv.f

Hey bestie 💖 this is the DLARTV(3) page in the Library Functions Manual, header path and all: /home/abui...RC/dlartv.f(3). Yes, it’s giving “Fortran subroutine with main character energy.”

✨ SYNOPSIS ✨

Functions/Subroutines

subroutine DLARTV (n, x, incx, y, incy, c, s, incc)

DLARTV applies a vector of plane rotations with real cosines and real sines to the elements of a pair of vectors. Slay. 🦋

🎀 Function/Subroutine Documentation 🎀

subroutine DLARTV (integer n, double precision, dimension( * ) x, integer
    incx, double precision, dimension( * ) y, integer incy, double
    precision, dimension( * ) c, double precision, dimension( * ) s, integer
    incc)

DLARTV applies a vector of plane rotations with real cosines and real sines to the elements of a pair of vectors. (Yes, the same glow-up, but now with the full signature.) 💅

🎯 Purpose 🎯

Here’s the literal math vibe, no cap:

!>
!> DLARTV applies a vector of real plane rotations to elements of the
!> real vectors x and y. For i = 1,2,...,n
!>
!>    ( x(i) ) := (  c(i)  s(i) ) ( x(i) )
!>    ( y(i) )    ( -s(i)  c(i) ) ( y(i) )
!>

🌈 Parameters 🌈

• N — N is INTEGER, and it’s the number of plane rotations to be applied. 🌀
• X — X is DOUBLE PRECISION array, dimension (1+(N-1)*INCX). This is the vector x. 💖
• INCX — INCX is INTEGER. It’s the increment between elements of X. Important: INCX > 0. 🚨
• Y — Y is DOUBLE PRECISION array, dimension (1+(N-1)*INCY). This is the vector y. 🫶
• INCY — INCY is INTEGER. It’s the increment between elements of Y. Important: INCY > 0. 🚨
• C — C is DOUBLE PRECISION array, dimension (1+(N-1)*INCC). These are the cosines of the plane rotations. 🌸
• S — S is DOUBLE PRECISION array, dimension (1+(N-1)*INCC). These are the sines of the plane rotations. ✨
• INCC — INCC is INTEGER. It’s the increment between elements of C and S. Important: INCC > 0. 🚨
