dlartv.f-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.Function/Subroutine Documentation 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) ) 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. Author: Univ. of Tennessee Univ. of California Berkeley Univ. of Colorado Denver NAG Ltd.

dlargv.f-SYNOPSIS

Functions/Subroutines subroutine dlargv (N, X, INCX, Y, INCY, C, INCC) DLARGV generates a vector of plane rotations with real cosines and real sines.Function/Subroutine Documentation subroutine dlargv (integerN, double precision, dimension( * )X, integerINCX, double precision, dimension( * )Y, integerINCY, double precision, dimension( * )C, integerINCC) DLARGV generates a vector of plane rotations with real cosines and real sines. Purpose: DLARGV generates a vector of real plane rotations, determined by elements of the real vectors x and y. For i = 1,2,...,n ( c(i) s(i) ) ( x(i) ) = ( a(i) ) ( -s(i) c(i) ) ( y(i) ) = ( 0 ) Parameters: N N is INTEGER The number of plane rotations to be generated. X X is DOUBLE PRECISION array, dimension (1+(N-1)*INCX) On entry, the vector x. On exit, x(i) is overwritten by a(i), for i = 1,...,n. INCX INCX is INTEGER The increment between elements of X. INCX > 0. Y Y is DOUBLE PRECISION array, dimension (1+(N-1)*INCY) On entry, the vector y. On exit, the sines of the plane rotations. 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. INCC INCC is INTEGER The increment between elements of C. INCC > 0.
