Is it possible to create a subclass in Matlab using a superclass written in Java?

Hi,

I am quite new to object oriented programming, so hopefully I manage to explain my issue in a clear way.

I have a bunch of classes written in Java that I imported and used successfully in Matlab.

What I haven't been able to do however, is use a java interface as a Matlab superclass.

When I create a new class using:

classdef mySubclass < javaInterface

      (methods and properties of the class)

end

I get the error message:

Error using mySubclass
The specified superclass 'javaInterface' contains a parse error, cannot be found on MATLAB's search path, or is shadowed by another file with the same name.

I checked that the Interface java class was imported properly by typing methods('javaInterface').

When I looked around in the literature for similar issues, I couldn't find anything relevant to my case.

Do you know if it's even possible to use a java interface as a Matlab Superclass?

Thank you so much for your time, and I apologize in advance if this is a basic question.

Hi Claire,

As the error message suggests, it is searching for a MATLAB class in the search path and is not able to find one.

You will not be able to subclass a Java class in a MATLAB class hierarchy. However, you will be able to use the Java classes in MATLAB by adding them to the javaclasspath (static/ dynamic and importing the required components).

Hope this helps.
