Origin Ver 8.0 SR6, WinXPSP2.
How to fit my function if it is the result of differential equation solution?
I have the differential equation like dF/dt=MyFun(F,t,T,P,A,B,C...) where t,T,P are variables and A,B,C are parameters.
I have experimental data at four columns: t,T,P,Fexper.
I know how to solve my differential equation using NAG library and obtain Fteor at parameters A,B,C and at the same points as in experimental data of t,T,P.
Now I wand to fit Fteor to Fexper by variation of A,B,C...
There is no analytical formula for F(t,T,P,A,B...)
How can I solve my problem? |

Hi,
We are sorry that Origin/OriginPro does not provide the ability of fitting implicit function in current version.
