We use Class to define an instance of an object that carries data & the methods to be implemented on that data. Step #5įinally, to calculate the area of the rectangle simply call ‘getArea’ method of the class ‘Rectangle’ using the object created: Using the Constructor function to create an object of the class:įunction newRectangle = Rectangle (colour, width, height)Īs we can see in the output, all the properties are assigned to the object RectObject.

Next, we will assign values to the object RectObject:Īs we can see in the output, all the values are now assigned to the object RectObject. Since we have not passed any values yet, the object is created with empty values. Specifying the object as a member of the class:Īs we can see in the output, an object is created with properties the same as the properties of the class Rectangle. An object can also be created using constructors. Next, we will create an object by specifying the object as a member of the class.įor this, we will create an instance of a particular rectangle object. Next, we will define the function to be implemented on the data collected above:įunction to be implemented is defined using a ‘methods’ block.Īrea = newRectangle.Height * newRectangle.Width As stated before, it is the same as the name of the class created by us. Please observe the name of the file in the Input. So, for our example, the name of the file will be ‘Rectangle.m’Īs we can see in the output, we have obtained the properties of our class ‘Rectangle’.

Please note that the class created must be stored in a file with ‘.m’ extension and the name of this file must be the same as the name of the class. In our example, action will compute the areaįor a class, we can check the properties using ‘properties’ command as below: Action to be performed on the properties or data in the above step. Properties for ‘rectangle’ object will include:Ģ. Properties or data values for our object. To define our object ‘rectangle’, we will be defining the following 2 parameters:ġ. Using this method, we define the name of our class, properties, or data values of an object in our class, and methods or functions which we want to be implemented on the objects.įor our class ‘Rectangle’, ‘rectangle’ will be an object. In MATLAB, we use the ‘classdef ‘method to define a class. Here are the following syntax mention below Step #1 – Defining the Class For our understanding, we will create a class that will be used to calculate the area of a rectangle.

Let us now learn how to create a class in MATLAB. The methods or functions implemented on data The data that the object contains referred to as propertiesĢ. Hadoop, Data Science, Statistics & othersġ.
