Changes made on Curve fitting toolbox, how to extract data from fit?

Hi,

My question might be very silly but I want to know what happened to the GUI interface of the curve fitting toolbox that allows you to extract information from the fit? I want to extract data points from fitted curve and it was very easy in old versions of curve fitting toolbox. Now, in the new version, I can not find the GUI interface to do so. I could calculate data points from fit, their first and second derivatives at different number of data.

Besides, how easily I can determined these values in the command line?

Many thanks

Save the fit from the toolbox. Use feval to get the data from the fit.
