So I use,</p> <p>input_args = {'PMLInside', false};<br /> sensor_data = kspaceFirstOrder2D(kgrid, medium, source, sensor, [], input_args{:});</p> <p>But it shows that,<br /> Error using kspaceFirstOrder_inputChecking (line 1206)<br /> Optional input parameters must be given as param, value pairs</p> <p>I don't know why. How should I define this parameter to set the boundary outside my grid?</p> <p>Thanks. </p>
