This book provides a clear and precise exposition of modern numerical techniques. It is designed as a suitable text-book for engineering and science students up to the postgraduate level. Each method is illustrated by a number of solved examples followed by properly graded problems, some of which have been selected from various University and professional examination papers. Basic Concepts & General Information has been given in the begining. As programming is becoming more and more popular, Numerical techniques using C and C++ have been explained in the last three chapters. Each of the programs has been successfully run on a computer and tested on examples solved earlier. This will enable the reader to become more conscious of the power of modern computational techniques. An exhaustive list of ‘Objective Type of Questions’ is given in an Appendix besides Answers to Problems and Standard Tables. An introdcution to MATLAB for technical computation is also given at end.
