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