Function/Subroutine Documentation

subroutine zlartv (integerN, complex*16, dimension( * )X, integerINCX, complex*16, dimension( * )Y, integerINCY, double precision, dimension( * )C, complex*16, dimension( * )S, integerINCC)

ZLARTV applies a vector of plane rotations with real cosines and complex sines to the elements of a pair of vectors.

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) )

Parameters:

N

N is INTEGER
The number of plane rotations to be applied.

X

X is COMPLEX*16 array, dimension (1+(N-1)*INCX)
The vector x.

INCX

INCX is INTEGER
The increment between elements of X. INCX > 0.

Y

Y is COMPLEX*16 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 COMPLEX*16 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.
