zlartv: applies a vector of complex plane rotations with real cosines to elements of the complex vectors x and y

NAME

ZLARTV - applies a vector of complex plane rotations with real cosines to elements of the complex vectors x and y

SYNOPSIS

SUBROUTINE ZLARTV(
N, X, INCX, Y, INCY, C, S, INCC )

    
INTEGER INCC, INCX, INCY, N

    
DOUBLE PRECISION C( * )

    
COMPLEX*16 S( * ), X( * ), Y( * )

PURPOSE

ZLARTV applies a vector of complex plane rotations with real cosines to elements of the complex vectors x and y. For i = 1,2,...,n
x(i) :=        c(i)   s(i) x(i) )

y(i)    -conjg(s(i))  c(i) y(i) )

ARGUMENTS

N (input) INTEGER
The number of plane rotations to be applied.
X (input/output) COMPLEX*16 array, dimension (1+(N-1)*INCX)
The vector x.
INCX (input) INTEGER
The increment between elements of X. INCX > 0.
Y (input/output) COMPLEX*16 array, dimension (1+(N-1)*INCY)
The vector y.
INCY (input) INTEGER
The increment between elements of Y. INCY > 0.
C (input) DOUBLE PRECISION array, dimension (1+(N-1)*INCC)
The cosines of the plane rotations.
S (input) COMPLEX*16 array, dimension (1+(N-1)*INCC)
The sines of the plane rotations.
INCC (input) INTEGER
The increment between elements of C and S. INCC > 0.
