Very limited application of least squares. It gives you the plotted curves of original and plotted data with the equation in polynomial form. you can also evaluate that polynomial at different points for prediction.
1.it would be best viewed on 1024x768.
2. if you copy and paste data in data feed boxes then press enter also.
i used sexy.m(a file contributed here)for displaying equation in polynomial form
Looks nice but not very convenient and, above all, not very usefull. The standard Matlab's "Basic Fitting" tool does much more and much better, and does not require any additional toolbox! I would therefore suggest to submit this file in the category "GUI Tools and Examples" instead of "Statistics and Probability".
