Hi,
As per my understanding, you want to enable functionality such as pointers for your application but MATLAB does not provide such a feature. We can make it work but with some modification. When you do the following:
person = struct('name', 'John Doe', 'age', 21, 'scores', [90, 85, 88]);
person2 = person;
person.name = 'Kevin';
MATLAB will create a new variable person2 and will copy all the values from person to person2 and from then onwards they will be two separate entities and hence changing person.name to ‘Kevin’ won’t modify the field under person2.
We can do some modification to achieve what we decide by making a class which inherits from handle in MATLAB and then defining struct as a property of the class. Here is how it is done:
%Make a class file
classdef dummy<handle
properties
person = struct('name', 'John Doe', 'age', 21, 'scores', [90, 85, 88]);
end
end
%In the main file instantiate and use
Person1 = dummy;
Person2 = Person1;
%Change some property of Person1
Person1.person.name = 'Kevin';
disp(Person2.person.name);
%You will see that it displays Kevin, hence we achieved the desired behaviour
I am attaching the documentation for the handle class in MATLAB:
I hope this will help!
