Hi,
I'm looking for a curve-fitting package to do a specific
problem in chemical kinetics. (Sorry for the long
description)
The function to be fitted is
I = exp(-kf1 * tf) * (kex/(kex + kf2)) *
(1 - exp( -(kf2 + kex)* tex))
kex is a known constant.
I, tf, and tex are known variables.
I need to optimize values of kf1 and kf2 against
sets of several (I, tf, tex) values.
Does anyone know of a program that'll do this sort
of fit? Nothing I have (facsimilie, Kalidegraph,
Mathematica) can do it. I'd prefer something for
a Sun or Mac that I can get for free.
Thanks!
