The input argument to the r method of the BasicClass class will be an instance of BasicClass. You will need to access the property of that object explicitly; there's no implicit "Because this identifier matches the name of a property, we'll use the value of that property on the instance of the class in this method" behavior.
While you could make a new BasicClass object to perform the recursive call to the r method, I would instead use a class-related function that is not a method to do that recursion. Put all of the next block of code into a file named BasicClass.m.
classdef BasicClass
properties
Value
end
methods
function [Result] = r (myobj)
Result = recurseComputeR(myobj.Value);
end
end
end
function Result = recurseComputeR(myobjValue)
if myobjValue > 0
Result = recurseComputeR(myobjValue-1)*1000+2;
else
Result = 2;
end
end
Use this class like:
obj = BasicClass;
obj.Value = 2;
answer = r(obj)
You should receive 2002002 in the variable answer.
