Hello!
I want to fit data to a function with two intervals but identical parameters. How can I do that, without fixing the parameter values in the second interval?

let's say for example

y = P1 + P2*x ; for 0 < x < x1 and
Y = P1 * exp(P2*x) ; for x < x1

1. how can I define a function like this?
2. how can I get origin to fit on this function?

Thanks a lot!
Cheers
Stevo
