Detailed Description

template<typename Lhs, typename Rhs, int ProductType = internal::product_type<Lhs,Rhs>::value>
class Eigen::ProductReturnType< Lhs, Rhs, ProductType >

Helper class to get the correct and optimized returned type of operator*.

Parameters
Lhsthe type of the left-hand side
Rhsthe type of the right-hand side
ProductModethe type of the product (determined automatically by internal::product_mode)

This class defines the typename Type representing the optimized product expression between two matrix expressions. In practice, using ProductReturnType<Lhs,Rhs>::Type is the recommended way to define the result type of a function returning an expression which involve a matrix product. The class Product should never be used directly.
