get_vt() [10/12]

template<typename T >

void cntr::get_vt	(	const int	m,
		const int	i,
		cdmatrix &	G_vt,
		herm_matrix_timestep_view< T > &	G,
		herm_matrix_timestep_view< T > &	Gcc
	)

Returns the right-mixing component of a general contour function at given times.

Purpose

Returns the right-mixing component \( G^\lceil(\tau_m,t_i) \) at given times \( t_i\) and \( \tau_m\). The hermitian conjugate \(G^\ddagger\) is used.

Parameters

m	[int] Index of time \( \tau_m\) .
i	[int] Index of time \( t_i\) .
G_vt	[cdmatrix] The right-mixing component (returned to an eigen3 matrix).
G	[herm_matrix_timestep_view] Contour function G
Gcc	[herm_matrix_timestep_view] Hermitian conjugate \(G^\ddagger\) of \(G\).
