how to put boundary/limit in fsolve?
Posted:

Hi,
I need to fit data from our experiment using fsolve. The equation is X1*exp(t/X2) + X3*exp(t/X4) + X5. A simple equation.
From experimental data, we can estimate the values of X1 and X5 within a certain range. I am using fsolve function.
My question are: 1. Do you know a way which I can put a range/limit for X5 and/or X1 values before/during the iteration process?
I could not find any clues from Optim. manual, am I missing something?
2. Are there fitting programs/functions like fsolve which can be used for noncontinuous functions reliably?
thanks robi
