Useful example for what???

1) Why do you forumulate your solveblock so complicated? You may use the full vectors instead:

2) If your goal is a fit, a regression, you would rather use MinErr instead of Find:

3) What you have done with the solve block can be done more efficiently using polyfit(s) or regress

4) In case one day you dont are after a polynomial fit, you would rather user genfit:

If I am missing your point, please explain.
