PolyFit Tutorial: Best Polynomial Fit for MultiReagent Reaction in ENGR45, Slides of Computational Methods
In this tutorial, learn how to find the best fitting polynomial for a multireagent reaction in engr45 using polyfit. Determine the j, s, and r2 values for polynomials of degrees 1-4, and use the low-r2 polynomials to estimate the amount of reagent required to minimize curing time. The tutorial includes matlab files and a digital data table.
