Brian,
Thanks for the reply. I will certainly apply what you are suggesting

Hi,
I am using the gsl_multimin_fminimizer with the Nelder Mead ("ambeba")
algorithm and want to
put some constraints on the parameters that are optimized. Like I don't
want them to become negative.
Is there a way to do this and if so, what is it?
Thanx,
Ines

everyone, is it possible to do following thing with non-linear least

hi everyone,
I have one more question about nonlinear least squares fitting, I will use the
example from GSL online manual. I copied it to my program and just changed the
equation to
y = Ai(1-exp(-t/ti)) + Ap(1-exp(-t/tp))
with parameters Ai, Ap, ti, tp
I set correct partial derivations too, t
