33 This algorithm provides a simple way of analyzing the quality of the empirical
34 interpolation obtained by a reduced basis for complete states, using
35 measurements at precise points.
36
37 The results displayed by default are simple statistics related to the
38 normalized errors between the interpolation with a reduced basis and the
39 complete states we seek to represent on the reduced basis. The test requires a
40 reduced basis and a set of optimal measurement positions, and uses
41 pseudo-measurements from each complete state ("*snapshot*") included in the
42 given test set.
43
44 Please note: to be consistent, this test must use the same mathematical norm as
45 that used to construct the reduced basis. As the norm is chosen by the user
46 when defining the test, the norm used to construct the reduced basis must be
47 verified.
