WebPeriodic Recurrent Class Deﬁnition •Consider a recurrent class. •Let us group all the states into d disjoint groups of states S 1,···,S d; a group has to contain at least one state. •Such a recurrent class is called periodic if there exists at least one group (of states) in the chain that is visited with a period WebIn R, we use the setClass () function to define a class. For example, Here, we have created a class named Student_Info with three slots (member variables): name, age, and GPA. Now to create an object, we use the new () function. For example, Here, inside new (), we have provided the name of the class "Student_Info" and value for all three slots.
