get_gtr() [1/4]

template<typename T >

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

inline

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