This Smath session is nearly immense but only 25 sec in my steam engine laptop.

It is rich of utilities and model functions. The original data set from Viktor
aimed at Mathcad Minerr parameters to the ODE system ... That, Smath can't do
directly but indirectly very simple. For this particular Kinetics, nice data
from ODE are just data, not analytical as such. This session attempted to all
the Kinetics be expressed in analytical functions ... done.
Naturally, the job will have to be re-done for other Kinetics parameters.
The difficulty is around fitting model function to each Kinetics branch
as well as to those of their derivatives. That last part is RemToDo.
Observe carefully the A, B, C Genfit. From robust to difficult via the
technique Genfit-Observer.
Just too bad I know nothing about Kinetics !
Will surely guide Kinetics Designers of that style ODE.

Cheers ... Jean

... suite/end => last two model fit D2(x), D3(x)
