Does anyone know how to use an IF statement with ODE's? I am trying to create an IF statement sigma > 0 , tau > 0 if dx(3,1) > 0, dx(1,1) > 0 and sigma = 0 , tau = 0 otherwise
Do not use an if statement inside an ODE... Not unless the if statement will always follow the same branch for any one invoca...

Is it possible to add Interactive Tasks into App Designer
No, Interactive Tasks are specific to Live Script. You would need to build appropriate sliders and drop-down menus yourself.
