✨ subroutine slartv ✨

subroutine slartv (integer n, real, dimension( * ) x, integer incx, real,
    dimension( * ) y, integer incy, real, dimension( * ) c, real, dimension(
    * ) s, integer incc)

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

🎯 Purpose

SLARTV 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 The number of plane rotations to be applied.
• X — X is REAL array, dimension (1+(N-1)*INCX) The vector x.
• INCX — INCX is INTEGER The increment between elements of X. INCX > 0.
• Y — Y is REAL array, dimension (1+(N-1)*INCY) The vector y.
• INCY — INCY is INTEGER The increment between elements of Y. INCY > 0.
• C — C is REAL array, dimension (1+(N-1)*INCC) The cosines of the plane rotations.
• S — S is REAL array, dimension (1+(N-1)*INCC) The sines of the plane rotations.
• INCC — INCC is INTEGER The increment between elements of C and S. INCC > 0.
