Summary

This authoritative book guides readers in developing a strong working knowledge of MATLAB to solve a wide range of engineering problems. Since solving these problems usually involves writing relatively short, one-time-use programs, the authors demonstrate how to effectively develop such programs in MATLABprograms that are compact yet readable, easy to debug, and execute fast. Emphasis is on using MATLAB to obtain solutions to several classes of engineering problems, so technical material is presented in summary form only.
