## ◆ convolution_timestep_omp() [4/4]

template<typename T >
 void cntr::convolution_timestep_omp ( int omp_num_threads, int tstp, herm_matrix< T > & C, herm_matrix< T > & A, herm_matrix< T > & B, T beta, T h, int SolveOrder )

Returns convolution $$C = A\ast f\ast B$$ at a given time step.

Purpose

Computes contour convolution C=A*f*B of the objects with class 'herm_matrix' at a given time step 't=nh'. Here we assume that A and B are hermitian. Works for a scalar and square matrices. openMP parallelized version.

Parameters
 omp_num_threads [int] The number of openMP threads to be used. Set to the number of threads in the current team. tstp [int] index 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 B [herm_matrix] contour Green's function beta inversed temperature h time step interval SolveOrder [int] integrator order
