<p>
Caveat: Because the interpolation scheme requires that derivatives be
specified at the sample points, those are approximated with finite
differences (using the 2-points symmetric formulae).
Since their values are undefined at the borders of the provided
interpolation ranges, the interpolated values will be wrong at the
edges of the patch.
The <code>interpolate</code> method will return a function that overrides
<a href="../../../../../../org/apache/commons/math3/analysis/interpolation/BicubicInterpolatingFunction.html#isValidPoint(double,%20double)"><code>BicubicInterpolatingFunction.isValidPoint(double,double)</code></a> to
indicate points where the interpolation will be inaccurate.
