Octave and MATLAB for Engineering Applications

Andreas Stahel. Octave and MATLAB for Engineering Applications

For many engineering tasks extensive computations or visualizations are required. The well established Matlab and Octave (a very similar open source software) are excellent tools for modeling, computing and visualization. This book will help the reader to acquire basic knowledge and elementary programming skills with Octave/Matlab.
