a></code> (see the <a href="example_na_source_smoothing.html">Source Smoothing Example</a>). To provide a valid comparison, the output of the reconstruction code <code><a href="kspaceLineRecon.html">kspaceLineRecon</a></code> must be compared to the <em>smoothed</em> version of the initial pressure used in the simulation. This can be achieved by explicitly using <code><a href="smooth.html">smooth</a></code> before passing the initial pressure to <code><a href="kspaceFirstOrder2D.html">kspaceFirstOrder2D</a>
