   Hello,

   I want to set the boundary layer outside the computational grid. So I use,

   input_args = {'PMLInside', false};
   sensor_data = kspaceFirstOrder2D(kgrid, medium, source, sensor, [], input_args{:});

   But it shows that,
   Error using kspaceFirstOrder_inputChecking (line 1206)
   Optional input parameters must be given as param, value pairs

   I don't know why. How should I define this parameter to set the boundary outside my grid?

   Thanks.

   Hi stang,

   You have an extra input containing square brackets which you should remove, i.e., you should instead use:

   sensor_data = kspaceFirstOrder2D(kgrid, medium, source, sensor, input_args{:});

   Brad.
