set_matrixelement() [1/2]

template<typename T >

void cntr::herm_matrix_timestep_view< T >::set_matrixelement	(	int	i1,
		int	i2,
		herm_matrix_timestep_view< T > &	g,
		int	j1,
		int	j2
	)

Set the matrix element of \(C_{[i1,i2]}\) for each component from \( g_{[i1,i2]} \)

Purpose

Set the matrix element \(C_{[i1,i2]}\) for each component from \( g_{[i1,i2]} \). If \(t>-1\) then ret,les,tv components are set, otherwise mat. Works for scalar or square-matrix contour objects.

Parameters

i1	Row index of herm_matrix_timestep_view
i2	Column index of herm_matrix_timestep_view
g	The herm_matrix_timestep_view from which the matrix element element is given
j1	Row index of herm_matrix_timestep_view
j2	Column index of herm_matrix_timestep_view
