zlartv.f(3) LAPACK zlartv.f(3)

zlartv.f -


subroutine zlartv (N, X, INCX, Y, INCY, C, S, INCC)
 
ZLARTV applies a vector of plane rotations with real cosines and complex sines to the elements of a pair of vectors.

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.
