Hi all,
I've an experiment data which collect from thin-film transistor.
Here, I would like to obtain the paramters (mark with red square) throuhg curve fitting.
I've tryed the cftool to do that, unfortunately, it's fail....becasue I'm new with the curve fitting with matlab.
Can anyone teach me how to start conduct it?
where,
W/L=0.25
VTH=3.11
VD=0.1

(1) Import the data using readtable(), e.g:
D = readtable('IdVg.xlsx');
v=table2array(D(:,1));
TR=table2array(D(:,2));
(2) Use custom equation in cftool and insert your formulation in terms x variable.

Use the coeffvalues function on the fit in the workspace to extract the coefficients. There are also a number of other functions you can call to obtain information about the fit.
