create a class that represents a state machine with states a and b in matlab

You can create a class for the state machine using Matlab's object-oriented programming features. Here's an example of a class that represents a state machine with two states, "a" and "b".

main.m
classdef StateMachine
    properties
        currentState
    end
    
    methods
        function obj = StateMachine()
            obj.currentState = 'a';
        end
        
        function nextState(obj)
            if obj.currentState == 'a'
                obj.currentState = 'b';
            else
                obj.currentState = 'a';
            end
        end
        
        function reset(obj)
            obj.currentState = 'a';
        end       
    end
end

The class has a property called currentState, which represents the current state of the state machine. The class has two methods, nextState and reset, which allow you to change the state of the state machine.

nextState switches the state machine to the next state in the sequence (i.e., from state "a" to state "b" or vice versa). reset sets the state back to the initial state ("a").

You can create an instance of this class using the following code:

main.m
myMachine = StateMachine();

You can then call the nextState method to switch between states:

main.m
myMachine.nextState();  % Switch to state "b"
myMachine.nextState();  % Switch back to state "a"

And you can reset the state machine using the reset method:

main.m
myMachine.reset();  % Set the state back to "a"
