Numerical methods

The presented text is an English version of the original textbook written in Polish ("Metody numeryczne"), published in 2013 (first edition) and 2026 (second edition) by OWPW (Oficyna Wydawnicza Politechniki Warszawskiej - the Warsaw University of Technology Publishing House). This second English edition differs a little from the first one published in 2014, the few errors found in the first edition have been only corrected and very minor improvements of the text and figures have been done.
The original version of the textbook (first edition) was written based on the author's long experience as a teacher of several courses on numerical methods, at the Faculty of Electronics and Information Technology, Warsaw University of Technology, mainly the course "Numerical Methods" taught in Polish for ICT students and in English for Electrical and Computer Engineering students. The textbook summed up the experience of a long series of previously prepared Lecture Notes, available for students in electronic form at the web pages of the courses.
The author would like to express his gratitude to all students actively taking part in the courses, for all comments concerning the way of presentation, for indications of editorial errors. All these comments helped the author to improve the quality of this textbook.
