EZyRB: Easy Reduced Basis method

Model Order Reduction, roughly speaking, can be summarized in two parts: an offline and an online part. In the first, one constructs the database of solutions, or snapshots, for proper selected parameters. In the latter the database is used for a fast evaluation of the quatity of interest for a new parameter (see for example Schilders, Van der Vorst, and Rommes 2008; Hesthaven et al. 2016). Choices can be made either for the selection of the parameters in the construction of the database or on how the database is used to approximate the manifold of the snapshots.
