Commands: (Must be accessed from the library function, be sure to refresh libraries) *autofoil: Launches the autofoil wizard *autofoillegacy: (f1,f2,f3,f4) Takes the inputs and simplifies it using the FOIL method. For the legacy version however, you must include in this format: (f1,f2,f3,f4). Give the required inputs and you're done. Smiley The program is very straight-forward. But to keep nice with 2.0 users, I have also included a 'legacy' version inside the program file. In fact, with the recent 3.0 update, a wizard for AutoFoil has been implemented.

Cheesy ) This program is also very easy to work with. That's why I figured out AutoFoil! It saves time with the whole FOIL thing and saves paper space! (And it helps me be lazy. When working with many math equations such as factoring or quadratic stuff, many (2x-4)(4x+2)-like (in format) strings come up and become very tedious to solve or simplify. One of these things that fail is 'FOIL'-ing, also known as First Outer Inner Last. One of my pet peeves about my nSpire CAS, is that: although it is marketed as a CAS, it sometimes doesn't work the way I expect from a $150 device. The outputs from the program are 1) a statement as to whether the convergence critera was met, 2) the iteration matrix showing the progression of estimated parameters and associated sum-of-square errors, 3) the ANOVA matrix, 4) a vector of the standard error of the regression and R^2 stats, 5) a matrix of the estimated parameters with their standard errors, t values and probabilities, and 6) the fitted equation (as sometimes simplified by the software). (Update: corrects a problem created by the latest update.) This program fits data to an arbitrary function, i.e., to functions that are not necessarily linear in their parameters.
