Considering following matlab loop:</p> <pre><code>% loop through the scan lines for scan_line_index = 1:number_scan_lines % load the current section of the medium medium.sound_speed = sound_speed_map(:, medium_position:medium_position + Ny - 1, :); medium.density = density_map(:, medium_position:medium_position + Ny - 1, :); % run the simulation sensor_data = kspaceFirstOrder3D(kgrid, medium, transducer, transducer, input_args{:}); % extract the scan line from the sensor data scan_lines(scan_line_index, :) = transducer.scan_line(sensor_data); % update medium position medium_position = medium_position + transducer.element_width; end</code></pre> <p>If I understand correctly, if I need to move this to C++, I should basically create HD5 input file for every call to <code>kspaceFirstOrder3D</code> and them call the C++ application with that input file. So, is it correct that if I want to reproduce this example, I need to create <code>number_scan_lines</code> HD5 input files and then call the C++ program on each of them?</p> <p>Assuming this is correct, the next matlab line in the example is:</p> <p><code>scan_lines(scan_line_index, :) = transducer.scan_line(sensor_data);</code></p> <p>How do I then create the scan lines array from the C++ outputs? </p>
