Computational Technologies - A G Churbanov Kartoniert (TB)

In this book wedescribe the basic elements of present computational technologies that use the algorithmic languages C C++. The emphasis is on GNU compilers and libraries FOSS for the solution of computational mathematics problems and visualization of the obtained data. At the beginning a brief introduction to C is given with emphasis on its easy use in scientific and engineering computations.We describe the basic elements of the language such as variables data types executable statements functions arrays pointers dynamic memory and file management. After that we present some observat ions on the C++ programming language.We discuss the issues of program compiling linking and debugging. A quick guide to Eclipse is also presented in the book. The main features for editing compiling debugging and application assembling are considered.As examples wesolve the standard problems of computational mathematics: operations with vectors and matrices linear algebra problems solution of nonlinear equations numerical differentiation and integration interpolation initial value problems for ODEs and so on. Finally basic features ofcomputational technologies are illustrated with model problems. All programs are implemented in C C++ with using the GSL library. Gnuplot is employed to visualize the results of computations.
