The book is the second edition of the first volume of the 5-volume MATLAB + Simulink series. For the first time, one book describes the latest versions of this MATLAB R2006*/2007*/2008 system and its main Simulink extension (versions 5, 6 and 7) performing block situational modeling. These systems are leading in numerical calculations and in mathematical, block simulation and situational visual-oriented modeling of various systems and devices. The highest degree of visualization of the results of work . Serves as a powerful operating environment for the application and development of hundreds of expansion packages in the latest areas of science and technology For engineers, researchers, students and teachers of universities and universities . The book was prepared with the support of the systems developer The Math Corporation. Works, Inc. (United States).
