Generate a Java Package and Build a Java Application
Supported platform: Windows®, Linux®, Mac
![]()
This example shows how to use the Library Compiler app to create a Java® package for a MATLAB® function. You can then pass the generated package to the developer who is responsible for integrating it into an application. This example also shows how to call the Java package from a Java application. The target system does not require a licensed copy of MATLAB.
Create Function in MATLAB
In MATLAB, examine the MATLAB code that you want packaged. For this example, open
makesqr.m located in .
At the MATLAB command prompt, enter
makesqr(5) .
The output is:

After creating your Java packages, you can call them from a Java application. The Java application that you create uses the sample Java driver code generated during packaging. The Java driver code calls the Java packages, and it is based on the sample MATLAB file you selected in previous setup steps.
These steps are also explained in the
GettingStarted.html file in for_redistribution_files_only folder. Before starting, make sure that you Install and Configure the MATLAB Runtime, and that you have the Java Development Kit installed.
