h different spacings. This means both the speed and accuracy of the reconstruction  are dependent on the method used for this interpolation. This can be controlled via the optional input parameter <code>'Interp'</code> which is passed directly to <code><a href="matlab: doc interp2">interp2</a></code>. By default, this is set to <code>'*nearest'</code> which optimises the interpolation for speed. The accuracy of the interpolation can be improved by setting <code>'Interp'</code> to <code>'*linear'</code> or <
