Function for solving iteratively over a fixed interval

Hey there,

So I'm attempting to use matlab to solve a problem iteratively. Basically S is a function of itself and I want to do this for t=0:500.

S=So-(X/Y)*exp(((u*S)/(K+S))*t)

Again, the only real variable here is S.

How do I code this?

What I've attempted to do is to use both fzero and the solve functions. Neither are giving me any sort of acceptable answer.

Thanks in advance!

Show us your code you used with the "fzero" Approach - it should work.

Best wishes

Torsten.
