Detailed Description

template<typename Lhs, typename Rhs, int ProductType>
class Eigen::ProductReturnType< Lhs, Rhs, ProductType >

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

Parameters:

Lhs	the type of the left-hand side
Rhs	the type of the right-hand side
ProductMode	the 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.
