Passing struct from Java to Matlab

Dear all,

I would like to create a Matlab struct in Java and then pass it to Matlab.

To do this, I created the following member function of my already existing class:

public Struct pollMatlab(){
    return new Struct("p", 2, "q", 3);
}

This was inspired by the documentation here.

I also imported the packages

import com.mathworks.engine.*;
import com.mathworks.matlab.types.*;

However, when I call the function, I don't get a nice struct, but an object of type

com.mathworks.matlab.types.Struct@...

The keys and values contained in this object are as expected. I then tried to convert the java-object to its Matlab equivalent by simply using struct (inspired from the documentation here). This, however, yields an empty struct.

I have the feeling that using the matlab.types.Struct should immediately lead to a proper Matlab struct. Am I missing something?

Any help would be greatly appreciated.

Best regards

Torsten Knüppel
