how Can I fit the multiple data sets by using the curve Fitting Tool in MATLAB?

I have been searching, and can't find out how to fit a curve to multiple data sets.

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.
