How can I pass a ragged array of Java primitive types to a Java function from MATLAB?

I want to pass a nonrectangular array of doubles to a function that is a member of a Java class. A Java function can return a ragged array to MATLAB which is then converted to a cell array, but I cannot pass this array back to a Java function.

An example of a ragged array is:

A= [1 2 3; 

        4 5;   

        6 7 8]

The ability to create Java primitive types is not available in MATLAB.

It is possible to create ragged arrays of Java objects by creating the Java objects and concatenating them together. For example, you can create a ragged array of the Java "Double" class as follows:

A=[java.lang.Double(1) , java.lang.Double(2) ,  java.lang.Double(3) ;

       java.lang.Double(4) , java.lang.Double(5) ;

       java.lang.Double(6) , java.lang.Double(7) ,  java.lang.Double(8)]
