Help in implementing ode45 in app designer

        methods (Static)
        function dydt = odefun(app,t3,Y,A)
                    dydt = 0;       
                    dydt = A+2*t3;
            end
        
        end    
    
        properties (Access = public)
            t = 0:0.005:20;
            initial_x=2;
            A=0;
            t1=0; x=0;
        end
            
        methods (Access = private)

            % Button pushed function: Button
            function ButtonPushed(app, event)
                [app.t1,app.x] = ode45(@(t,Y) app.odefun(t,Y,app.A), app.t, app.initial_x);
                
                plot(app.UIAxes,app.t1,app.x,'-o');
            end
        end    
            
            
            

This is my sample code. If I save the same function (odefun) as a separate file in the current directory, this code works. However, if I include the same function as methods (Static), I get the following error: 'Not enough input arguments...'. I remember, I read somewhere, that the parameters need to be initialized, which I have done. Still the code does not work. Any help in this regard will be appreciated. Thank you!

Static methods don't assume that the app is passed as the first argument, so remove "app" from the arg list

methods (Static)

    function dydt = odefun(t3,Y,A)
        dydt = 0;       
        dydt = A+2*t3;
    end

end
