localizer_inertia_complex()

subroutine spectral_localizer::localizer_inertia::localizer_inertia_complex	(	complex(kind=dp), dimension(:, :), intent(in)	matrix,
		integer, intent(out)	positive,
		integer, intent(out)	negative,
		integer, intent(out)	status )

Count inertia by pivoted Hermitian LDL^dagger, without orthogonalizing the AO basis.

Parameters

matrix	Hermitian matrix; input is not modified
positive	Number of positive eigenvalues
negative	Number of negative eigenvalues
status	0 resolved, 1 singular, -1 invalid data, -4 factorization failure

Note

Pivot magnitudes are not eigenvalues or a metric-aware protection gap.

		integer, intent(out)	negative,
		integer, intent(out)	status )

Native real symmetric LDL^T inertia, without converting to complex storage.

Parameters
