In MATLAB, you can replicate the functionality of Python's “__getitem__” and “__setitem__” methods by overloading the “subsref” and “subsasgn” methods within a class. These methods enable you to define custom behavior for indexing operations.
Kindly refer to the code snippet below for an example.
classdef MyClass
properties(Access=public)
Data
end
methods
function obj = MyClass(data)
% Constructor to initialize the Data property
obj.Data = data;
end
function value = subsref(obj, S)
% Override subsref to define custom indexing behavior
switch S(1).type
case '()'
% Handle parentheses indexing
value = obj.Data(S.subs{:});
otherwise
error('Not a valid indexing expression');
end
end
function obj = subsasgn(obj, S, value)
% Override subsasgn to define custom assignment behavior
switch S(1).type
case '()'
% Handle parentheses indexing
obj.Data(S.subs{:}) = value;
otherwise
error('Not a valid indexing expression');
end
end
end
end
For more information on “subsref” and “subsasgn” methods kindly refer following MathWorks Documentation.
I hope this will be helpful.
