Construct an object given another object of that class

What I want to do can be accomplished with the following :
classdef X methods function obj = X(x) obj.x = x; end
function y = f(obj,x)
y = eval([class(x) '(' num2str(-x.x) ')']);
end
end
properties
x;
end
end
a = X(2); b = a.f(a);
but the use of eval is ugly and slow. Is there not a better way to get the class of an object from the object itself?
