Answer 1

A quick google brought up this http://j-integra.intrinsyc.com/support/com/doc/other_examples/Matlab.htm

Alternatively, can you execute your matlab function from the command line? If so you can use Runtime.getRuntime().exec("your matlab function")

Answer 2

MATLAB Builder JA is one option to use MATLAB code in Java. This is a non free toolbox for creating a jar file from MATLAB code in order to be imported to Java. Take care of the restrictions concerning jar file creation.

Using Java classes inside MATLAB is much easier, as you can instantiate Java classes in MATLAB code. Undocumented Matlab is one valuable resource for Java integration in MATLAB.

Check Using Sun Java Classes in MATLAB Software for the official information provided by The MathWorks.

Answer 3

matlabcontrol is a Java API which will allow you to call your image processing functions or scripts and return the results to Java. To get started, take a look at the walkthrough.

Answer 4

As of R2016b you can use official MATLAB Engine API for Java, which seems to allow same functionality as matlabcontrol.
