SYNOPSIS

package 'Mypackage';
with 'Photonic::Roles::Reorthogonalize';
.
.
.
$self->_checkorthogonalize;

DESCRIPTION

Role consumed by AllH objects to be used in a Photonic calculation. Estimates orthogonalization errors and makes a full reorthogonalization of Haydock states when required. This version works for both Hermitian operators with real Haydock coefficients, and for non Hermitian operators with complex Haydock coefficients.
