Function/Subroutine Documentation
subroutine dlargv (integer n, double precision, dimension( * ) x, integer incx, double precision, dimension( * ) y, integer incy, double precision, dimension( * ) c, integer incc)
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.
