zlar2v.f(3) LAPACK zlar2v.f(3)

zlar2v.f -


subroutine zlar2v (N, X, Y, Z, INCX, C, S, INCC)
 
ZLAR2V applies a vector of plane rotations with real cosines and complex sines from both sides to a sequence of 2-by-2 symmetric/Hermitian matrices.

ZLAR2V applies a vector of plane rotations with real cosines and complex sines from both sides to a sequence of 2-by-2 symmetric/Hermitian matrices.
Purpose:
 ZLAR2V applies a vector of complex plane rotations with real cosines
 from both sides to a sequence of 2-by-2 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) )
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; the elements of x are assumed to be real.
Y
          Y is COMPLEX*16 array, dimension (1+(N-1)*INCX)
          The vector y; the elements of y are assumed to be real.
Z
          Z is COMPLEX*16 array, dimension (1+(N-1)*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+(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.
