write a singleton in matlab

A Singleton is a design pattern that restricts the instantiation of a class to one object, providing a global point of access to that object. In Matlab, a singleton can be implemented using the following steps:

1. Create a private constructor that prevents the creation of multiple instances of the class.
2. Create a private static instance of the class within the class definition.
3. Create a public static method that returns the static instance of the class.

Here is an example implementation of a Singleton class in Matlab:

main.m
classdef SingletonClass
    % Private properties
    properties (Access = private)
        % Define private properties here
    end
    
    % Private Methods
    methods (Access = private)
        function obj = SingletonClass()
            % Constructor code here
        end
    end
    
    % Static Properties
    properties (Access = private, Constant)
        instance = SingletonClass();
    end
    
    % Static Methods
    methods (Static)
        function obj = getInstance()
            % Access to the static instance of the class
            obj = SingletonClass.instance;
        end
    end
end

To create an instance of the Singleton class, use the static getInstance() method:

main.m
myObject = SingletonClass.getInstance();

The myObject variable now references the static instance of the SingletonClass, which can be accessed as a normal object.
