   Hello
   I have a simply question.I would like to save the matrix 4D of pressure for all the Grid with using the kspaceFirstOrder3D function without changing this function.Is it possible and how ?
   Thank you for your answer.

   Hi Guy,

   I don't know if I well understand your question but if you want to record pressure for all the grid points at each time step you just need to use the full sensor :
   sensor.mask = ones(Nx,Ny,Nz);
   I hope it's that you asked.
   Best regards,

   Alex

   Hi math.guy,

   Another option is to use a sensor mask cover the whole domain defined as cuboid corners, i.e.,

   sensor.mask = [1; 1; 1; Nx; Ny; Nz];

   This is equivalent to the approach mentioned by Alex, however, the output is instead a 4D matrix index as (x_ind, y_ind, z_ind, t_ind).

   Brad.
