subroutine dlartv (integerN, double precision, dimension( * )X, integerINCX, double precision, dimension( * )Y, integerINCY, double precision, dimension( * )C, double precision, dimension( * )S, integerINCC)¶
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) )
N
Author:
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.
