   Hi,
   In ex02_simple_example_kWaveArray_sensor.m, I have reset "dx=0.5e-5;dy=0.5e-5". A problem occurred:
   Error in kspaceFirstOrder_inputChecking (line 616)
   [sensor.mask, order_index, reorder_index] = cart2grid(kgrid, sensor.mask, flags.axisymmetric);

   Error in kspaceFirstOrder2D (line 537)
   kspaceFirstOrder_inputChecking;

   Error in ex02_simple_example_kWaveArray_sensor (line 82)
   sensor_data_point = kspaceFirstOrder2D(kgrid, medium, source, sensor);

   How to fix this problem

   If you decrease the grid point spacing, the domain size will be smaller (much smaller in your case). So you will also need to reduce the size of the elements in the kWaveArray so they fit on the grid.
