This textbook is an introduction to Scientific Computing, in which
several numerical methods for the computer-based solution of certain classes
of mathematical problems are illustrated. The authors show how to compute the
zeros or the integrals of continuous functions, solve linear systems,
approximate functions using polynomials and construct accurate approximations
for the solution of ordinary and partial differential equations. To make the
format concrete and appealing, the programming environments Matlab and Octave
are adopted as faithful companions. The book contains the solutions to several
problems posed in exercises and examples, often originating from important
applications. At the end of each chapter, a specific section is devoted to
subjects which were not addressed in the book and contains bibliographical
references for a more comprehensive treatment of the material.
