function uses another function and that is used by the first function like a cycle

Hi everyone,

I have three functions which using each other in a while loop and for loop. like :

1. f uses p function which is array
2. u uses f,
3. p uses u
4. and f uses again p (updated)

so it is a cycle. Imagine I have space variable with 101 nodes and time vector. so for each time the program has to solve f,u,p for each space node. They need to be updated to be used inside of other functions..

So how can I locate these three functions?

Meva - please clarify what you mean by f uses p function which is array. What is the array?

[Meva]

Hi Geoff Sorry I was unable to touch. u, p functions are array ( 1*101 matrix ).I mean for example every p(i) depends on u(i). Every u(i) depends on f . Every f depends on p(i).

Meva - please post your code, describing what its current (unexpected) behaviour is and the behaviour that it should exhibit.
