MATLAB Object-Oriented Programming

Create a Single, Self-Contained Class Definition File

Create a single, self-contained class definition file in a folder on the MATLAB® path. The
name of the file must match the class (and constructor) name and must have the .m
extension. Define the class entirely in this file. You can put other single-file classes in this
folder.

The following diagram shows an example of this folder organization. pathfolder is a
folder on the MATLAB path.

ClassNameA.m Contains classdef and methods for ClassNameA

pathfolder

ClassNameB.m Contains classdef and methods for ClassNameB

ClassNameC.m Contains classdef and methods for ClassNameC

...

ordinaryFunction.m A function on the path

Distribute the Class Definition to Multiple Files

If you use multiple files to define a class, put all the class-definition files (the file
containing the classdef and all class method files) in a single @ClassName folder. That
class folder must be inside a folder that is on the MATLAB path. You can define only one
class in a class folder.

pathfolder

ClassNameB.m

ClassNameA.m Contains classdef

@ClassNameA

classMethod.m Class method in separate !le

Contains entire class de!nition

A path folder can contain classes defined in both class folders and single files without a
class folder.

Group Classes with Package Folders

The parent folder to a package folder is on the MATLAB path, but the package folder is
not. Package folders (which always begin with a + character) can contain multiple class
