Purpose:ZLAR2V applies a vector of complex plane rotations with real cosines from both sides to a sequence of 2by2 complex Hermitian matrices, defined by the elements of the vectors x, y and z. For i = 1,2,...,n ( x(i) z(i) ) := ( conjg(z(i)) y(i) ) ( c(i) conjg(s(i)) ) ( x(i) z(i) ) ( c(i) conjg(s(i)) ) ( s(i) c(i) ) ( conjg(z(i)) y(i) ) ( s(i) c(i) ) N

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