NAME
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.
