Hello, I am trying to learn classes in Matlab here is a basic question. How can I write two classes A and B in order to represent following structur?
My first class is A and second class is B. Let A has two property as p and q and B has also two property as m and n. Moreover, one of class is subclasses of other.
A.p=1;
A.q=2;
B.m=3;
B.n=4;
A.B=B; %Minor question :) which one is a subclass A or B?
%Hence
A.B.m %should be 3
A.B.n %should be 4

I have read lots of articles and I have writen some classes but I can not combine classes. When I try to make one of them subclases I get the following resault.
A.p=1
A.q=2
A.m=3
A.n=4

You have defined A as a subclass of B and the result you see is as documented, i.e. what you should expect.

It is a convention to use upper case for the first letter in a class name and lower case for instancies/objects
Try
>> a = A();
>> a.b.m
ans =
3
where
classdef A
properties
p = 1;
q = 2;
b = B;
end
end
and
classdef B
properties
m = 3;
n = 4;
end
end
.
One more example
>> A.B.m
ans =
3
where
classdef A
properties ( Constant )
p = 1;
q = 2;
B = B();
end
end
and
classdef B
properties ( Constant )
m = 3;
n = 4;
end
end
However, I don't think this is what you really ask for.

Thank you very much for your answer. That is what I excatly want. Also thank you for correcting me about upper and lower cases. Where can I find these rules. For example, all cracters in global variables should be writen as UPPER CASE like.

There is very little on naming conventions in the Matlab documentation.
google for "object oriented programming naming conventions"
See Java Code Conventions
See the blog Book Review: The Elements of MATLAB Style
