set_matrixelement() [1/6]

template<typename T >

void cntr::herm_matrix< T >::set_matrixelement	(	int	tstp,
		int	i1,
		int	i2,
		herm_matrix_timestep< T > &	g
	)

Sets given matrix elements of all components at time step tstp to the components of a given herm_matrix_timestep of a scaler type.

Purpose

Sets the (sub-) matrix elements (i1,i2) of all components at time step tstp to the components of a given herm_matrix_timestep of scaler type.

Parameters

tstp	The time step at which the components are set.
i1	First index for submatrix.
i2	Second index for submatrix.
g	The herm_matrix_timestep from which the time step is copied.
