overload the assignment operator in matlab

In MATLAB, the assignment operator = cannot be overloaded directly. However, you can define a custom method that performs the required operation and call it instead of using the standard assignment operator.

Here's an example of overloading the assignment operator in a custom class:

main.m
classdef MyClass
    properties
        value
    end
    
    methods
        function obj = MyClass(value)
            obj.value = value;
        end
        
        function obj = assign(obj, value)
            % Perform the required operation here
            obj.value = value + 1;
        end
    end
end

In this example, the assign method is defined to perform the operation of adding 1 to the assigned value. To use this method instead of the standard assignment operator, you can call it directly:

main.m
a = MyClass(2);
a = a.assign(3);

After this operation, a will have a value of 4.

Note that this technique of overloading the assignment operator is not truly overloading the operator, as you are not actually modifying the behavior of the operator itself. However, it can be a useful workaround in cases where you need to perform more complex operations on assignment.
