Please Help Me About Sub and Super Classes
显示 更早的评论
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

Search for "Defining a Subclass" in the help. As far I can judge, you describe an association.

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.

There is very little on naming conventions in the Matlab documentation.
google for "object oriented programming naming conventions"
