In this book, an introduction of the Technical computing language MATLAB, for mechanical engineering students was introduced. Many of engineers and scientists use MATLAB to analyze and design the systems and products transforming the world, where the matrix- based MATLAB language is the most world's most natural way to express computational mathematics. The main objective of this book is to provide the students with the opportunity to improve their skills using MATLAB environment to implement algorithms and to teach the use of MATLAB as a tool in solving problems in mechanical engineering. This book includes the coverage of basics of MATLAB and applications of MATLAB software to solve problems in statics and dynamics mechanical systems.
