Why can't you use input arguments? They are the natural way of passing data to functions.

Persistent variables have very specific use cases, but don't go near them otherwise. In the right circumstances they are very useful, in all other circumstances they are as disastrous as global variables and the vast majority of coding falls into the 'all other circumstances' category.

because it is giving me an error ,apparently you cant use other input parameters expect x and t to use the ode command
