In Appdesigner, I create a app.UIAxes and a app.Button, how to write a callback to use this app.UIAxes to plot a step response using the command 'step(tf)' when I push down this Button.

R = app.Resistencia.Value;

C=app.Condensador.Value;

H=tf([0 1],[1 1/(R*C)])

step(app.UIAxes,H)

You can extract the output of the step function and use the "plot" function in App Designer. Here is an example callback function for the Button :

          % Button pushed function: PlotButton
          function PlotButtonPushed(app, event)
              tf = 1:3:100;
              a = [-0.5572,-0.7814;0.7814,0];
              b = [1,-1;0,2];
              c = [1.9691,6.4493];
             sys = ss(a,b,c,0);
             [y,t] = step(sys);
             plot(app.UIAxes,y(:,:,1));
          end
