There seems to be an issue with inheritance when using
"matlab.mixin.Heterogeneous."
To illustrate consider two objects (code at bottom): Child, which inherits from Parent. The superclass method "changeParentVariable" is useless only when everything inherits from matlab.mixin.Heterogeneous. One would hope that root of inheritance (handle or matlab.mixin.Heterogeneous) would be immaterial. How can I make correct the behavior of matlab.mixin.Heterogeneous?
Behavior when everything inherits from "handle:"
>> test = Child(1,2) test = Child with properties: childVariable: 2 parentVariable: 1 >> changeParentVariable(test,3) >> test test = Child with properties: childVariable: 2 parentVariable: 3
Behavior when everything inherits from "matlab.mixin.Heterogeneous:"
test = Child(1,2) test = Child with properties: childVariable: 2 parentVariable: 1 >> changeParentVariable(test,3) >> test test = Child with properties: childVariable: 2 parentVariable: 1
…the superclass method was unable to modify the object when everything inherits from "matlab.mixin.Heterogeneous."
THE CODE
classdef Parent < handle % or matlab.mixin.Heterogeneous
properties parentVariable = []; end methods function obj = Parent() obj.parentVariable = 0; end function changeParentVariable(obj,a) obj.parentVariable = a; end end end classdef Child < Parent properties childVariable = []; end methods(Sealed) function obj = Child(a,b) obj = obj@Parent(); obj.parentVariable = a; obj.childVariable = b; end end end
