Follow-up Comment #5, bug #48749 (project octave):
By the way,
n = numel(A) is equivalent to prod(size(A))
is not appropriate for Java arrays,
because they are usually ragged: the entries of Object[][]
in general do not have the same length.
Thus numel cannot be determined by product but by recursively summing up.
That may be the reason why matlab defines size(arr) for java arrays arr as it
does.
