Matlab class

When creating matlab class applications, it is important to organize the various building blocks of your software into related groups. For example, a custom numerical solver may require several configuration parameters and routines to perform its full set of calculations. Everything a user will need to properly execute this solver is defined in this class, matlab class. An object is an instance of a class.

Attributes modify the behavior of classes and the members defined in the class-definition block. For example, you can specify that methods are static or that properties are private. The following sections describe these attributes:. Class definitions can provide information, such as inheritance relationships or the names of class members without actually constructing the class. See Class Metadata. See Specifying Attributes for more on attribute syntax. Value classes represent independent values. Value objects contain the object data and do not share this data with copies of the object. Values objects passed to and modified by functions must return a modified object to the caller. Handle classes create objects that reference the object data. Copies of the instance variable refer to the same object.

Basic commands like whos display the class of each value in the workspace. This information helps MATLAB users recognize that some values are characters and display as text while other values are double precision numbers, and so on. Some variables can contain different classes of values like structures. These classes include numeric, logical , char , cell , struct , and function handle. For example, you could define a class to represent polynomials. This class could define the operations typically associated with MATLAB classes, like addition, subtraction, indexing, displaying in the command window, and so on.

Here is the BasicClass definition after adding the features discussed in this topic:. Do you want to open this example with your edits? All parents must have the same nonzero size, which determines the size of the returned object. Implementing Operations with Class Methods Methods, or the operations that can be performed on the object, are specified as a list of functions in a methods block. Engineering Exam Experiences. For information on constructors, see Class Constructor Methods. In this way, a code author can easily group all the related data and functions for a software system and a user can easily find and use all the capabilities the code author has developed. Assign a value to the Value property using the object variable and a dot before the property name:. For example, they let you prohibit modification of a property, hide a property, or cause it to be calculated dynamically. For information on class properties, see Property Syntax. Main Content.

Most methods take the object as an input argument for example, obj and access the object properties by referencing this variable for example, obj. For example, BasicClass defines a property and two methods that operate on the data in that property: Value — Property that contains the numeric data stored in an object of the class roundOff — Method that rounds the value of the property to two decimal places multiplyBy — Method that multiplies the value of the property by the specified number. You prohibit modification of a property by setting the Constant attribute. For example, suppose that you want to add two BasicClass objects.

Everything a user will need to properly execute this solver is defined in this class. MATLAB classes support function and operator overloading, controlled access to properties and methods, reference and value semantics, and events and listeners. For example, they let you prohibit modification of a property, hide a property, or cause it to be calculated dynamically.
