## ◆ convolution() [1/3]

template<typename T >
 void cntr::convolution ( herm_matrix< T > & C, herm_matrix< T > & A, herm_matrix< T > & Acc, herm_matrix< T > & B, herm_matrix< T > & Bcc, integration::Integrator< T > & I, T beta, T h )

Returns the result of the contour convolution of two 'herm_matrix' objects

Purpose

Calls convolution routines to compute contour convolution C=A*B. The objects A,B and C are of the class 'herm_matrix'. Works for a scalar and square matrices.

Parameters
 C [herm_matrix] Matrix to which the result of the convolution is given A [herm_matrix] contour Green's function Acc [herm_matrix] complex conjugate to A B [herm_matrix] contour Green's function Bcc [herm_matrix] complex conjugate to B I [Integrator] integrator class beta inversed temperature h time step interval
