Hi,

I'm looking for a way of constructing an object depending on configuration. Basically, I have something like this

classdef MyClass < handle
    ...
    methods
        ...
        function foo = foo()
            do something
        end
        function boo = boo()
            do something
        end
    end
end

The properties of the class are the same, and I expect every instance of this class to have the foo and boo methods. However, I have multiple possibilities for these methods. Say for each I have 3 different implementations, which I can combine, giving a total of 9 behaviours for class MyClass. One example is: foo can either do some computations and output a value, or it can read this value from a table, or it can generate a random number. I also can at any time create a new implementation, like generating a random number but this time with a different distribution, so it would be nice to have each implementation in a different file.

What I want to do is to construct an instance of this class by saying: implement foo like this and boo like this.

Are there any suggestions?
