Originpro 2016 SR0
Operating System:Windows 8
I want to fit experimental data with the following functions
P(V) = Ps*tanh(V-Vc/2d) where d is a separate term and
Qnsw(V) = C*V + integration from 0 to t (V/R)dt
So the toal function which has to fit is like
Qtot(V) = P(V) + Qnsw(V)
I have calculated separately the value of Qnsw and is in a separate column.
SO the fitting function will be
Qtot(V) = P(V) + col(D)
My query is how can I add col (D) into Origin nonlinear equation for fitting?
Thanking you,
Jayant |

Hi,
I think you can change the function into:
Qtot(V) - col(D) = P(V)
in which Qtot(V) - col(D) can be indicated to NewQtot(V).
In order to calculate the value of NewQtot(V), you can add a new column in worksheet and set the column values as “ col (Qtot(V)) – col(D)”.
At last, you can do nonlinear fitting with the new function:
NewQtot(V) = P(V)
Hope the information helps.
Regards,
Yuki

Non linear equation fitting is an important concept in statistics. There are many techniques to solve this problem. Refer http://academic-essay-writing-service.blogspot.in/ for more details. |
