Curve fitting tool - extract modified data

Hi everyone,

I'm using the curve fitting tool for linear regression and to remove outliers for my data.

Below is an example of what I'm trying to do.

How can I recieve the new data for y where the one outier identified has been removed?

Thanks

xdat = [1; 2; 3; 4; 5; 6; 7; 8; 9; 10]
ydat = [ 100; 85; 66; 50; 40; 70; 25; 20; 15; 2]
%scatter(xdat,ydat)

f = fittype( 'poly1' );

% Fit model to data.
fit1 = fit( xdat, ydat, f);

% Link with code: https://de.mathworks.com/help/curvefit/removing-outliers.html
fdata = feval(fit1,xdat); 

%Set standard deviation to 0.5 
% Identifies outliers with deviation from baseline model
I = abs(fdata - ydat) > 0.5*std(ydat); 
outliers = excludedata(xdat,ydat,'indices',I);

% refit model to data with outliers excluded
fit2 = fit(xdat,ydat,f, 'Exclude',outliers)
