Detailed Description

template<typename ValueType, typename TensorType, class Device>
class Stokhos::StochasticProductTensor< ValueType, TensorType, Device >

Bases defined by combinatorial product of polynomial bases.

Bases: \prod_{j=0}^{N-1} P_k(x) \forall j and k \in M(j) Where: P_k is a polynomial of degree k Where: <P_a,P_b> is the the integral on [-1,1] Where: <P_a,P_b> is the Kronecker delta \delta_{a,b} thus the polynomials are normalized with respect to this inner product.

Where: N = the number of variables expanded via polynomial bases Where: M(j) = the degree of a particular variable

Where: \psi_I(x) = is one basis function and I is a multi-index of rank N, denoting one function from each variable's polynomial bases.

Were: <\psi_I,\psi_J,\psi_K> is the integral on [-1,1]

The bases space is sparse due to orthogonality within the expansion.
