The mapping of Slice interfaces revolves around the idea that, to invoke a remote operation, you call a member function on a local class instance that is a proxy for the remote object. This makes the mapping easy and intuitive to use because making a remote procedure call is no different from making a local procedure call (apart from error semantics).

An empty array denotes the null proxy. The null proxy is a dedicated value that indicates that a proxy points "nowhere" (denotes no object)a dedicated value that indicates that a proxy points "nowhere" (denotes no object).

Interface Inheritance in MATLAB

Inheritance relationships among Slice interfaces are maintained in the generated MATLAB classes. For example:

interface A { ... }
interface B { ... }
interface C extends A, B { ... }

The generated code for CPrx reflects the inheritance hierarchy:

classdef CPrx < APrx & BPrx
    ...
end

Given a proxy for C, a client can invoke any operation defined for interface C, as well as any operation inherited from C's base interfaces.
