“This introductory book should be useful to undergraduate students in mathematics and engineering. … The approach to each topic appears to have been carefully thought out, both as to the mathematical treatment and to the pedagogical presentation. The end result is a quite satisfactory book for undergraduate classroom use or even self-study.” (Christian Lavault, Mathematical Reviews, July, 2019)
