you can solve equations for unknowns, easiest with the solve app. But there is the no ready to use optimization procedure built in. I wrote such a procedure you can find here: https://www.hpmuseum.org/forum/thread-16426.html
Perhaps this helps.

One last question: if I have to interpolate a series of data: X = {7,2,6,4,5} Y = {6,2,4,9,3}, how can I utilize your program ?
