Answer 1

If you want changing data outside your function (aka side effects) use classes instead of structures. Class must be a handle.

classdef MutableStruct < handle
    properties
        field1;
        field2;
    end
    methods
        function this = MutableStruct(val1, val2)
            this.field1 = val1;
            this.field2 = val2;
        end
    end
end
