23 * Classes for evaluating ''Monomials'' on any order
24 * for all reference element type.
25 * For a simplex topology these are the normal
26 * monomials for cube topologies the bimonomials.
27 * The construction follows the construction of the
28 * generic geometries using tensor products for
29 * prism generation and duffy transform for pyramid
30 * construction.
31 * A derivative argument can be applied, in which case
32 * all derivatives up to the desired order are
33 * evaluated. Note that for higher order derivatives
34 * only the ''lower'' part of the symmetric tensor
35 * is evaluated, e.g., passing derivative equal to 2
36 * to the class will provide the vector
37 * (d/dxdx p, d/dxydx p, d/dydy p,
38 * d/dx p, d/dy p, p)
39 * Important:
40 * So far the computation of the derivatives has not
41 * been fully implemented for general pyramid
42 * construction, i.e., in the case where a pyramid is
43 * build over a non simplex base geometry.
44 *
45 * Central classes:
46 * 1) template< GeometryType::Id geometryId, class F >
47 * class MonomialBasisImpl;
48 * Implementation of the monomial evaluation for
49 * a given topology and field type.
50 * The method evaluate fills a F* vector
51 * 2) template< GeometryType::Id geometryId, class F >
52 * class MonomialBasis
53 * The base class for the static monomial evaluation
54 * providing additional evaluate methods including
55 * one taking std::vector<F>.
56 * 3) template< int dim, class F >
57 * class VirtualMonomialBasis
58 * Virtualization of the MonomialBasis.
59 * 4) template< int dim, class F >
60 * struct MonomialBasisFactory;
61 * A factory class for the VirtualMonomialBasis
62 * 5) template< int dim, class F >
63 * struct MonomialBasisProvider
64 * A singleton container for the virtual monomial
65 * basis
