Writing Matlab functions for Java classes

Hi,

Suppose that I have a Java class, foo. Is there a way to
write a Matlab function that will be only invoked for
objects of type foo (or for its descendants)? For example, I
would like to write a function "sum" s.t. if x is of type foo,

sum(x)

will invoke my function and not the built-in one. With
Matlab classes (pre-7.6), I can put the Matlab function to
the @foo directory. Is there something similar for Java
classes?

Many thanks,
Stano

You could write a sum method for your java class. As long as the return type for the method was something that Matlab is happy with (double, int, boolean, a instance of the foo class, etc) then you can call the method with
>> out = sum(foo);
or the more traditional
>> out = foo.sum;
