Detailed Description

template<typename ordinal_type, typename value_type>
class Stokhos::ProductBasis< ordinal_type, value_type >

Abstract base class for multivariate orthogonal polynomials generated from tensor products of univariate polynomials.

The multivariate polynomials are given by
$\Psi_i(x) = \psi_{i_1}(x_1)\dots\psi_{i_d}(x_d)$
where is the dimension of the basis. This class adds methods for indexing the multivariate polynomial and getting the coordinate bases.

virtual const MultiIndex<ordinal_type>& Stokhos::ProductBasis< ordinal_type, value_type >::term ( ordinal_type i ) const

pure virtual

Get orders of each coordinate polynomial given an index i.

The returned array is of size $d$ , where $d$ is the dimension of the basis, and entry $l$ is given by $i_l$ where $\Psi_i(x) = \psi_{i_1}(x_1)\dots\psi_{i_d}(x_d)$ .

virtual ordinal_type Stokhos::ProductBasis< ordinal_type, value_type >::index ( const MultiIndex< ordinal_type > & term ) const

pure virtual

Get index of the multivariate polynomial given orders of each coordinate.

Given the array term storing $i_1,\dots,\i_d$ , returns the index $i$ such that $\Psi_i(x) = \psi_{i_1}(x_1)\dots\psi_{i_d}(x_d)$ .
