Website for Iterative Map / Lyapunov exponent

Smythe

Hi,

I want to produce a graph of how the Lyapunov exponent varies over a specific mathematical function.

Would anyone happen to know a website where I can type in a function and it will produce an iterative map for me?

Thank you.

Do you have access to mathematica? It is fairly easy to write a script that does that. Or you might try Wolfram alpha

Here is an example of me inputting the dynamical system y' = y

I have, but I have not used it before.

I'll take a look at that. Thank you.

I can send you a fairly straightforward script. You just type in the function and hit Shift+Enter. Or if you supply the functions and initial conditions I can have a go.

Thanks very much Morbert.

I was able to get things sorted out today.

I really appreciate your offering that though!
