To specify an Abstract class as a property for a MATLAB class, you must also specify a default value for the property which is a class that is derived from the abstract class you specified.
The code below demonstrates how the code you provided might be modified to accomplish this workflow.
classdefdemoClass
properties
TestPropertymatlab.mixin.Heterogeneous= rootClass
end
methods
functionobj = demoClass
% constructor that does not affect the property
end
end
end
classdefrootClass < matlab.mixin.Heterogeneous
methods
functionobj = rootClass
end
end
end
现在你应该能够实例化instance of "demoClass":
>> demoClass
ans =
demoClasswith properties
TestProperty: [1×1 rootClass]
