how to put boundary/limit in fsolve?

Sorry, I mispelled my return address in the previous one.

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 non-continuous functions reliably?
