Function/Subroutine Documentation

 

subroutine zlartv (integer N, complex*16, dimension( * ) X, integer INCX, complex*16, dimension( * ) Y, integer INCY, double precision, dimension( * ) C, complex*16, dimension( * ) S, integer INCC)

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.
