Developed through four semesters of teaching over more than a decade, An Introduction to Numerical Computation is, at its heart, a set of refined lecture notes from Wen Shen's course at Penn State University. The book's philosophy is to avoid the "encyclopedia approach"—surveying every possible algorithm—and instead focus on the most important computational methods, emphasizing the fundamental mathematical ideas that make them work.

The book "An Introduction to Numerical Computation" by Wen Shen is designed for undergraduate students, graduate students, and professionals who want to learn numerical computation. The book covers a wide range of topics, including:
