    %% Use Identical Fit Options in Multiple Fits  
% Modifying the default fit options object is useful when you want to set
% the |Normalize|, |Exclude|, or |Weights| properties, and then fit your
% data using the same options with different fitting methods. For example,
% the following uses the same fit options to fit different library model types.   

%%  
load census
options = fitoptions;
options.Normalize = 'on';
f1 = fit(cdate,pop,'poly3',options);
f2 = fit(cdate,pop,'exp1',options);
f3 = fit(cdate,pop,'cubicspline',options)
