User-Defined Handle Classes
So in MATLAB when the user wants to copy a handle an object, MATLAB copies doesn’t copy the data stored in that object’s properties.
Implementing Copy for Handle Classes in MATLAB
Handle classes are the special kinds of classes that allow the multi variables to the same object. so for implementing the copy functionality for the handle classes in MATLAB. firstly we need to define the method, in the class that creates a new object with the same properties as the original object.
So let’s see the syntax of creating the copy method for handling classes:
Syntax:
% Create a Handle Class
classdef MyClass < handle
properties
myProperty
end
end
Stepwise Implementation
For Implementing Copy for Handle Classes in MATLAB we have to follow the steps that are listed here.
Step 1: So firstly open the MATLAB editor and create a new file and define the class using the ‘classdef‘ keyword.
classdef MyClass % class definition goes here end
Step 2: After defining the class, inside the class define the properties and methods, and another element.
properties myProperty end
Step 3: Now we have to create the function with the name of the method, followed by the method definition.
methods function output = myMethod(obj, input) % method definition goes here end end
Step 4: Now we can create the class constructor instance of our class. and MATLAB provides the no. of input arguments.
methods function obj = MyClass(arg1, arg2) % constructor definition goes here end end
Step 5: To call a method, we have to use this line of code for method calls.
output = myObject.myMethod(input);
So, for accessing the properties and method of the object you can use the dot notation like “myObject.myProperty”.
So this is the overall implementation part of that cover the all above steps, which define how we can implement the copy for class handling.
Example:
Matlab
% Code classdef MyHandleClass < handle properties myProperty end methods function obj = MyHandleClass(arg1, arg2) if nargin > 0 obj.myProperty = arg1 + arg2; end end function newObj = copy(obj) % Create a new object of the same class newObj = feval(class(obj)); % Copy the property values newObj.myProperty = obj.myProperty; end end end |
% Create an instance of MyHandleClass myObject = MyHandleClass(2, 3); % Call the copy method to create a new instance newObject = copy(myObject); % Display the property values of the new instance disp(newObject.myProperty); % should display 5
This code creates an instance of MyHandleClass with myProperty set to 2+3=5. Then, it calls the copy method to create a new instance of MyHandleClass with the same property values. Finally, it displays the myProperty value of the new instance, which should also be 5.
Output:
Implementing Copy for Handle Classes in MATLAB
MATLAB is a (Matrix-Laboratory), matrix-based programming language platform that is majorly used to solve math work and real-time problems. it’s specifically designed for engineers and scientists to analyze and design systems. And also capable to solve real-time problems with some histogram equalization, and graphical representation.
So, in this article, we will look at implementing how we can handle the classes and also understand implementing Copy for Handle Classes in MATLAB, and see the overview of MATLAB, and what are the required terms.
