Internally, k-Wave uses a coordinate system with 0 in the centre. However, for the most part, the inputs are defined in grid coordinates (e.g., matrices of sound speed and density), and thus you can assume any coordinate origin you like.</p> <p>Brad </p> http://www.k-wave.org/forum/topic/about-coordinates#post-7839 Tue, 22 Sep 2020 02:16:28 +0000 123 7839@http://www.k-wave.org/forum/ <p>Hi ,</p> <p>i want to simulate sensor_data.p_max, sensor_data.p_rms like image at the bottom of the page(Simulating Transducer Field Patterns Example) coordinates:[~ -20, -10, 0, 10, 20 ~].<br /> but in my case, x-pos, y-pos are [0 20 40 ...~ (Nx)],[0 20 40 ...~ (Ny)].<br /> how can i simulate like that?</p> <p>Thank you </p>
