Is constructor method the only method that creates an object in a class definition?

Another way to ask this question is: how do I create a value class object as the output of a handle class ordinary method? For example,
classdef handleClassA < handle
properties
end
methods
function obj = handleClassA(varargin)
...
end
function ValueClassobj2 = unknownmethod(handleClassAobj, ValueClassobj1)
ValueClassobj2.property1 = ...
some_sort_function(handleClassAobj.property3, ValueClassobj1.property1);
...
end
end
end
If I do it the above way, the output is a struct with field property1, etc., not a object of a class.

In this simple example createDigraph only calls the constructor for the digraph class with a sample matrix returned from the bucky function (also included in MATLAB.)
In a "real world" scenario the myHandleClass object would probably have properties that the createDigraph method would use to compute the matrix with which you call the digraph constructor.

I think you are trying to do,
function ValueClassobj2 = unknownmethod(handleClassAobj, ValueClassobj1)
ValueClassobj2 = ValueClassobj1; %clone of obj1
ValueClassobj2.property1 = ...
some_sort_function(handleClassAobj.property3, ValueClassobj1.property1);
...
end
