MATLAB: Overloading Equality Operator for Arrays

Question

I have a class with the eq() operator overloaded, but I'm not sure the best way to make it work with object arrays, in a similar way to the way standard arrays work for equality. Here's the code that I have right now. For reference, the class is designed to work with spheres in 3D space, with a center [x, y, z] and a radius.

        function test=eq(a,b)
            if all(size(a.xyz)==size(b.xyz))
                if (a.radius==b.radius)
                    test=all(a.xyz==b.xyz);
                else
                    test=false;
                end
            else
                test=false;
            end
        end

Answer 1

Perhaps as follows

       function test=eq(a,b)
            test =  all([a.xyz]==[b.xyz]) & all([a.radius]==[b.radius]);
        end
