convolution_timestep() [4/4]

template<typename T >

void cntr::convolution_timestep	(	int	n,
		herm_matrix< T > &	C,
		herm_matrix< T > &	A,
		function< T > &	ft,
		herm_matrix< T > &	B,
		T	beta,
		T	h,
		int	SolveOrder
	)

Returns convolution of two hermitian matrices and a contour function at a given time step

Purpose

Computes contour convolution C=A*fxB of the hermitian matrices 'A' and 'B' and a time-dependent contour function 'F(t)' at a given time step 't=nh'. If 'n=-1', one performs Matsubara convolution with a function 'F(-1)', otherwise with 'F(t)' Works for a scalar and square matrices.

Parameters

n	[int] number of the time step ('t=nh')
C	[herm_matrix] Matrix to which the result of the convolution on Matsubara axis is given
A	[herm_matrix] contour Green's function (A=Acc)
ft	[function] the contour function F(t).
B	[herm_matrix] contour Green's function (B=Bcc)
beta	inversed temperature
h	time step interval
SolveOrder	[int] integrator order
