Opis

The book presents theory and applications of Laplace and z-transforms together with a Mathematica package developed by the author. The package substantially enhances the built-in Laplace and z-transforms facilities of Mathematica. The emphasis lies on the computational and applied side, particularly in the fields of control engineering, electrical engineering, mechanics (heat conduction, diffusion, vibrations). Many worked out examples from engineering and sciences illustrate the applicability of the theory and the usage of the package.

Recenzje

"This book is a very good tool for scientists and engineers that work in the fields of applications, especially on practical problems leading to ordinary differential equations which could be solved through Laplace transformation."(ZENTRALBLATT MATH)

"This monograph gives an introduction to the Laplace and z-transformations with emphases on applications in engineering and mechanics. Throughout the book a Mathematics package developed by the authors is used, which substantially enhances the built facilities of Mathematics. Both analytical and numerical aspects are treated."
