This text is designed to teach the basics of numerical analysis to students who need to apply the concepts of numerical computation in their other courses, rather than understand the theoretical basis of the mathematics. Significant changes in this edition include: the change of the FORTRAN code to pseudocode, allowing students to implement the algorithms in whatever language they choose (i.e. C, Pascal, or Fortran.); the text's incorporation of computer algebra (CAS) programming and algorithms which should give students a better understanding of the differences between the algorithms and the language; more effiecinet algorithms which aim to modernize the text's presentation.
