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.
Purpose:
!> !> 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 !> The number of plane rotations to be applied. !>
X
!> X is DOUBLE PRECISION array, !> dimension (1+(N-1)*INCX) !> The vector x. !>
INCX
!> INCX is INTEGER !> The increment between elements of X. INCX > 0. !>
Y
!> Y is DOUBLE PRECISION array, !> dimension (1+(N-1)*INCY) !> The vector y. !>
INCY
!> INCY is INTEGER !> The increment between elements of Y. INCY > 0. !>
C
!> C is DOUBLE PRECISION array, dimension (1+(N-1)*INCC) !> The cosines of the plane rotations. !>
S
!> S is DOUBLE PRECISION 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. !>
