I got around this by creating a 'copy' method for my class. Here is a simple example.
classdef myobj < handle % used to be matlab.mixin.Copyable so I could copy
properties
prop1
prop2
prop3
prop4
end
methods
function obj = myobj(prop1, prop2)
if nargin>0
obj.prop1 = prop1;
obj.prop2 = prop2;
end
end
function obj_out = copy(obj)
%COPY creates an exact copy of the object as a separate object
obj_out = myobj(obj.prop1,obj.prop2) %Create new instance of this object
%Copy the other properties of the class that aren't generated on construction
obj_out.prop3 = obj.prop3;
obj_out.prop4 = obj.prop4;
end
end
end
