Componentize Large Projects
MATLAB supports large-scale project componentization by allowing you to reference
other projects from a parent project. Organizing large projects into components facilitates
code reuse, modular and team-based development, unit testing, and independent release
of components.Projects can reference multiple other projects in a hierarchical manner. The project
reference hierarchy appears as a tree in the References view.From a parent project, you can- Access the project paths, entry-point shortcuts, and source control information for all
referenced projects. - View, edit, and run files that belong to a referenced project.
- Detect changes in referenced projects using checkpoints.
Add or Remove Reference to a Project
You can add new components to a project by referencing other projects.To add a reference to a project:1
On the Project tab, in the Environment section, click References. The Add
Reference dialog box opens.(^2) Browse to select the required project (.prj) file.
(^3) In the Referenced type field, select either Relative or Absolute. Select Relative if
your project hierarchy has a well-defined root relative to your project root. For
example, your project root might be a folder under source control. Select Absolute if
the project you want to reference is in a location accessible to your computer, for
example, a network drive.
(^4) To create a checkpoint when you add the project, select Set a checkpoint to detect
future changes. For more information about checkpoints, see “Manage Changes in
Referenced Project Using Checkpoints” on page 31-27.
(^5) Click Add.
When the referenced project loads, MATLAB adds the referenced project path to the
MATLAB search path and then runs or loads specified startup files. Similarly, when the
