Detailed Description

template<typename ordinal_type, typename value_type, typename node_type>
class Stokhos::CGDivisionExpansionStrategy< ordinal_type, value_type, node_type >

Strategy interface for computing PCE of a/b using only b[0].

Such a strategy is only useful when the division occurs in a preconditioner
