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.
