Apps are included in some MATLAB® products (such as Curve Fitting Toolbox™, Signal Processing Toolbox™, and Control System Toolbox™). In addition, you can write your own apps.
The apps gallery presents all the currently installed apps. To view the gallery, click the Apps tab and then, at the end of the Apps section, click the arrow.
If you install additional apps that you wrote or received from someone else, they appear in the apps gallery under My Apps.
The MATLAB Central File Exchange contains apps covering a range of applications. From there, you can download an app, install it in your apps gallery, and then run it with a single click.
