If not, simply summing the results from the C++ version won't give the same results unless you also correctly time shift the signals from the grid points that belong to each physical transducer element.

I noticed in the matlab code of the simulation, that there is some reconstruction going on durng the matlab-based simulation, which is not implemented in the c++ version.<br /> I just sum up the multiple channels which I get from the c++ sensor_data, but i didnt get the same result as in the matlab-based case.<br /> How do I get the faster c++ version to calculate the same results as the matlab based simulation? </p>
