Hi,
Use the below example to fit a curve
>>load hahn1
%Create a fit using the fit function,
% specifying the variables and a model type (in this case rat23 is the model type).
>>f = fit(temp,thermex,"rat23")
%Plot your fit and the data.
>>plot(f,temp,thermex)
>>f(600)
For single graph add values to x axis and y axis, for multiple graphs use for loop
For using multiple dataset with same polynomial or different polynomial, either by appending all values to x and y or use different "fit" and plot on single graph using "hold on" matlab function.
