Then, the reconstructed function can be evaluated at the evaluation samples by calling the adaptive tree visualization:
% AdaptiveTreeVisualization --in quadratic.2D.tree --samples quadratic.2D.evaluation.samples
This will output the evaluation positions and values:

Note that because the last evaluation position, (2,2), is outside the bounding box of the fitting samples, the function cannot be evaluated at this point and a value of "nan" is output.
