The function is represented on a regular :math:`\Omega_G` spatial grid of size
20x20 points. It is available in ADAO built-in test models under the name
-`TwoDimensionalInverseDistanceCS2010`. So here we first build a set of
-simulations of :math:`G`, then apply the DEIM-type decomposition algorithm to
-it, and derive some simple illustrations.

It can be seen that the singular values decrease steadily down to numerical
noise, indicating that around a hundred basis elements are needed to fully
