void cntr::convolution_timestep ( int  n,
herm_matrix< T > &  C,
herm_matrix< T > &  A,
herm_matrix< T > &  B,
beta,

int  SolveOrder 
)

Returns convolution of two hermitian matrices at a given time step

Purpose

Calls convolution routine to compute contour convolution C=A*B of two hermitian matrices at a given time step 't=nh'. The objects A,B and C are of the class 'herm_matrix'. 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)

B

[herm_matrix] contour Green's function (B=Bcc)

beta

inversed temperature

h

time step interval

SolveOrder

[int] integrator order
