ARGUMENTS
 N (input) INTEGER
 The number of plane rotations to be applied.
 X (input/output) COMPLEX*16 array, dimension (1+(N1)*INCX)
 The vector x; the elements of x are assumed to be real.
 Y (input/output) COMPLEX*16 array, dimension (1+(N1)*INCX)
 The vector y; the elements of y are assumed to be real.
 Z (input/output) COMPLEX*16 array, dimension (1+(N1)*INCX)
 The vector z.
 INCX (input) INTEGER
 The increment between elements of X, Y and Z. INCX > 0.
 C (input) DOUBLE PRECISION array, dimension (1+(N1)*INCC)
 The cosines of the plane rotations.
 S (input) COMPLEX*16 array, dimension (1+(N1)*INCC)
 The sines of the plane rotations.
 INCC (input) INTEGER

The increment between elements of C and S. INCC > 0.
