get_vt() [1/4]

template<typename T >

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

inline

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	[complex<T>] The right-mixing component (scalar GF).
G	[herm_matrix_timestep_view] Contour function G
Gcc	[herm_matrix_timestep_view] Hermitian conjugate \(G^\ddagger\) of \(G\).
