template<typename T >

void cntr::herm_matrix_timestep< T >::set_submatrix	(	int	tstp,
		std::vector< int > &	i1,
		std::vector< int > &	i2,
		herm_matrix_timestep< T > &	g,
		std::vector< int > &	j1,
		std::vector< int > &	j2
	)

Sets a (sub-) matrix of this contour object at a given time step to a (sub-) matrix of a given herm_matrix_timestep.

Purpose

Sets the (sub-) matrix of a two-time contour object \(C(t,t')\) the (sub-) of a given herm_matrix_timestep \(g\) according to \( C_{i_1(k) i_2(k)}(t,t') = g_{j_1(k) j_2(k)}(t,t') \) with \(k\) denoting an iterator of a subspace (at a given time step).

Parameters

tstp	Time step tstp.
i1	Vector of row indices of C.
i2	Vector of column indices of C.
g	The herm_matrix_timestep from which the (sub-) matrix is copied.
j1	Vector of row indices of g.
j2	Vector of row indices of g.
