Declare in MATLAB

In MATLAB, to declare a class, you can use the classdef keyword followed by the class name. Here's a simple example:

classdef MyClass
end

This creates an empty class called MyClass. You can add properties to this class using the properties keyword and methods using the methods keyword. Here's an example that includes properties and methods:

classdef MyClass
    properties
        Name
        Age
    end
    
    methods
        function obj = MyClass(name, age)
            obj.Name = name;
            obj.Age = age;
        end
        
        function sayHello(obj)
            fprintf('Hello, my name is %s and I am %d years old.\n', obj.Name, obj.Age);
        end
    end
end

In this example, we define a class called MyClass with two properties (Name and Age) and two methods (MyClass constructor and sayHello). The constructor takes two arguments (name and age) and assigns them to the respective properties. The sayHello method prints out a message using the properties.

To create an instance of this class, you simply call the constructor with the appropriate arguments, like this:

myObj = MyClass('John', 30);

This creates an object called myObj with the Name property set to 'John' and the Age property set to 30. You can then call the sayHello method on this object:

myObj.sayHello();

This will print out the message "Hello, my name is John and I am 30 years old."
