SYNOPSIS
Functions/Subroutines subroutine clar2v (N, X, Y, Z, INCX, C, S, INCC) CLAR2V 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. Function/Subroutine Documentation subroutine clar2v (integerN, complex, dimension( * )X, complex, dimension( * )Y, complex, dimension( * )Z, integerINCX, real, dimension( * )C, complex, dimension( * )S, integerINCC) CLAR2V 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: CLAR2V 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 array, dimension (1+(N-1)*INCX) The vector x; the elements of x are assumed to be real. Y Y is COMPLEX array, dimension (1+(N-1)*INCX) The vector y; the elements of y are assumed to be real. Z Z is COMPLEX 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 REAL array, dimension (1+(N-1)*INCC) The cosines of the plane rotations. S S is COMPLEX 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.
