get_gtr() [10/12]

template<typename T >

void cntr::get_gtr	(	const int	i,
		const int	j,
		cdmatrix &	G_gtr,
		herm_matrix_timestep_view< T > &	G,
		herm_matrix_timestep_view< T > &	Gcc
	)

Returns the greater component of a general contour function at given times.

Purpose

Returns the greater component \( G^>(t_i,t_j) \) at given times \( t_i\) and \( t_j\) from \(G^<(t_i,t_j)\) and \(G^\mathrm{R}(t_i,t_j)\).

Parameters

i	[int] Index of time \( t_i\) .
j	[int] Index of time \( t_j\) .
G_gtr	[cdmatrix] The greater component (returned to an eigen3 matrix).
G	[herm_matrix_timestep_view] Contour function G
Gcc	[herm_matrix_timestep_view] Hermitian conjugate \(G^\ddagger\) of \(G\).
