as_string()

template<class Mat >

std::string molpro::linalg::itsolv::subspace::as_string	(	const Mat &	m,
		int	precision = 6
	)

conjugate_transpose_copy()

template<class ML , class MR >

void molpro::linalg::itsolv::subspace::conjugate_transpose_copy	(	ML &&	ml,
		const MR &	mr
	)

Copies the conjugate transpose of mr into ml.

This is what relates the two off-diagonal blocks of a hermitian matrix; for a real element type it is the same as transpose_copy().

null_data()

template<typename T = double, EqnData... DataTypes>

auto molpro::linalg::itsolv::subspace::null_data

(

)

transpose_copy()

template<class ML , class MR >

void molpro::linalg::itsolv::subspace::transpose_copy	(	ML &&	ml,
		const MR &	mr
	)
