Hi, I just started playing with oop in Matlab. Dont have any other oop experience, so I seem to get lost in the first steps alerady. when I try to call teh following class
classdef myclass
%MYCLASS Summary of this class goes here
% Detailed explanation goes here
properties
t1
end
methods
function obj=myclass(arg1)
obj.t1=myclass.p(arg1);
end
end
methods (Static)
function p = pi(tol)
[n d]=rat(pi,tol);
p=n/d;
end
end
end
I always get the error
The class myclass has no property or method named 'p'.
How can I prevent that error?
Cheers

You need to replace
obj.t1=myclass.p(arg1);
with
obj.t1=myclass.pi(arg1);
You're making the (I suspect quite common) mistake of using the output variable name from the function instead of the name of the function itself.
If you make that change, the constructor runs:
>> m = myclass(3)
m =
myclass
Properties:
t1: 3
Does that do what you expect now?

Yes, if pi is not static, you can do
obj.t1 = obj.pi(arg1);
By the way, it would be better to avoid "pi" as a method name, so that it can't be confused with the inbuilt function pi.
