eld is recorded (i.e., <code>dt</code>). Consequently, the reconstructed initial pressure map typically will have a much finer discretisation in the x- (time) direction. By default, the reconstructed initial pressure distribution is not re-scaled or thresholded in any way. However, a positivity condition can be automatically enforced by setting the optional input parameter <code>'PosCond'</code> to <code>true</code>.</p>
