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
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.
