Thank you for your time and your response. You are amazing, You helped me with all my troubles. I have tried to write T1(I) but there was an error that Mathcad does not understand syntax(Can not understand syntax) I suppose that n and p must be a function of I and Pt must be a function only of parameters Nt,sighe..... But simple change of n to - n(I) and p to p (I) do not work.
But nevertheless, thank you so mush for your help.
With best regards,
The problem is that we cannot (or not as we would like to do) create a vector of functions.
As you don't use T2, you should do it the way I had shown in my previous post. T1(I) <-- Pt(I,...)[0
Note the vector index 0 at the end
Can I use the following (see attached) consistent Equality conditions constructions to fin 2 data sets Con1(I1) and R1(I1) by the same parameters.
I am solve set of equations and get n(I1) and p(I1) , so then I compare p(I1)*e*60=Con1(I1) and (p(I1)*60^2-n(I1)*925^2)/e*(p(I1)*60+n(I1)*925)^2 = R1.
I found out that if I delete the firstEquality condition fit does not change. So this can mean that I use wrong Mathcad syntax. Unfortunately, I did not find some similar programs.
Can someone experience with this?
