SYNOPSIS
Functions/Subroutines

CLAR2V applies a vector of plane rotations with real cosines and complex sines from
both sides to a sequence of 2by2 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 2by2 symmetric/Hermitian matrices.
Purpose:
CLAR2V 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) )
Parameters:
N
N is INTEGER
The number of plane rotations to be applied.
X
X is COMPLEX array, dimension (1+(N1)*INCX)
The vector x; the elements of x are assumed to be real.
Y
Y is COMPLEX array, dimension (1+(N1)*INCX)
The vector y; the elements of y are assumed to be real.
Z
Z is COMPLEX 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 REAL array, dimension (1+(N1)*INCC)
The cosines of the plane rotations.
S
S is COMPLEX array, dimension (1+(N1)*INCC)
The sines of the plane rotations.
INCC
INCC is INTEGER
The increment between elements of C and S. INCC > 0.
