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