Scilab is a powerful, open computing environment designed for engineering and scientific applications. This book gives a thorough description of Scilab's use including how to master its environment and programming language, the use of Scilab's integrated graphics, the integration of user provided functions, and a tour of its numerous applications toolboxes. This book provides students and professionals with an introduction to Scilab and its use in engineering/scientific problem solving. The book provides an overview of Scilab and includes an introductory, description of Scilab's programming language, syntax, useful functions, and graphics. Also described is how users can extend the functionality of Scilab by integrating custom Fortran and C programs as new Scilab primitives. The second part of the book presents the applications of Scilab to various scientific and engineering problems. Each of these topics is supported by a Scilab toolbox which is a rich collection of Scilab functions and primitives relevant to the application area. This book comes with a CD ROM containing the entire source code of Scilab as well as binary, executables for a variety of operating systems (all this is also available free via the internet). This CD ROM also contains Scilab programs illustrating many of the examples in the book.
