CallJavafromMATLAB

Directly call Java^®library functionality from MATLAB^®

You can access existing Java classes to use in the MATLAB workspace. For example, use built-in class packages, such as晶澳va.util, which are included in the Java language. See your Java language documentation for descriptions of these packages. You also can access classes defined in individual.classfiles, packages, or Java Archive (JAR) files, including classes you develop.

You can run MATLAB with your system version of the Java Runtime Environment (JRE™). For information about Java versions compatible with MATLAB, seeMATLAB Interfaces to Other Languages. To set the JRE path in MATLAB, calljenv. To set the path from the operating system prompt, callmatlab_jenv.

If instead you want to call MATLAB functions from Java applications, seeCall MATLAB from Java.
