I want to make a spline that is a function.

This one has 2 of the same y value wich is not good.

Help?

Hi Eelis! :-)


I'm not a chemist but I think/remember, that Titration curves should look like


t(x)= a/(b+exp(-x+c)) or t(x)=a/(1+exp(-x+b))+c


and not like polynoms.


The meaning of the parameters should a chemist know.


Kind regards

Perhabs you want to make your own spline-function

Even a spline will show strong oscillations

Perhaps you can do it piecewise (with 3 Points) as ggb do and union the functions by hand
