Correct, the categorical function / class constructor would define that
type.

No, Octave functions overload based on the argument type. Please have a
look at the docs on object oriented programming in Octave. There is a
simple example in the Octave source tree at examples/code/@polynomial.

You could look at the quaternion or symbolic packages for more complex
examples of custom types that overload built-in functions.
