Generic expression of a matrix where all coefficients are defined by a functor.
NullaryOp | template functor implementing the operator |
PlainObjectType | the underlying plain matrix/array type |
This class represents an expression of a generic nullary operator. It is the return type of the Ones(), Zero(), Constant(), Identity() and Random() methods, and most of the time this is the only way it is used.
However, if you want to write a function returning such an expression, you will need to use this class.
