I have Java code that I use in MATLAB, and I would like to convert between my custom Java Vector class and MATLAB vectors. MATLAB will automatically convert a MATLAB vector into a Java double[], which means that if my Vector class has the following constructor:

public Vector(double[] arr);

then I can write the following in MATLAB:

myJavaVec = Vector([1, 2, 3]);

This is excellent. I'd also like to go from my Java Vector to a MATLAB vector. Currently, I can do this via the following:

matlabVec = cell2mat(cell(myJavaVec.getAsJavaArray()));

I need only create the following function in my Java Vector class:

public double[] getAsJavaVector();

Is there any way to make this code even more concise? Ideally, I could have the following:

matlabVec = myJavaVec.getAsMATLABVector();
