Thank you to the University of Texas at Tyler students of Math 3380: Algorithms for Applied Mathematics. You were my guinea pigs as I initially drafted this manuscript as lecture notes, and as I have continued to massage the text over time.
Moreover, thank you to Rob Beezer, who made possible the conversion of this book to Mathbook XML, and to David Farmer, who used his excellent S2LX script to bulk-convert the original LaTeX source to Mathbook XML, which morphed into PreTeXt.
