Detailed Description

template<typename Lhs, typename Rhs, int ProductMode>
class ProductReturnType< Lhs, Rhs, ProductMode >

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 ei_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 or DiagonalProduct should never be used directly.
