Class to store coefficients of a projection onto an orthogonal polynomial basis.

Constructor & Destructor Documentation

template<typename ordinal_type, typename value_type>

Stokhos::OrthogPolyApprox< ordinal_type, value_type >::OrthogPolyApprox

(

)

Constructor with no basis.

Use with care! Sets size to 1 to store constant term

template<typename ordinal_type, typename value_type>

Stokhos::OrthogPolyApprox< ordinal_type, value_type >::OrthogPolyApprox	(	const Teuchos::RCP< const Stokhos::OrthogPolyBasis< ordinal_type, value_type > > &	basis,
		ordinal_type	sz
	)

Constructor with supplied size sz.

Normally sz should equal the basis size, however this is not enforced since other situations can arise, e.g., using a size of 1 for a constant expansion.

void Stokhos::OrthogPolyApprox< ordinal_type, value_type >::reset

(

const Teuchos::RCP< const Stokhos::OrthogPolyBasis< ordinal_type, value_type > > &

new_basis

)

Reset to a new basis.

This resizes array to fit new basis. Coefficients are preserved.
