Unformatted text preview: BASIC LAB EXERCISES USING LINUX, SUNIX AND MATLAB CONTENTS These notes borrow from the Colorado School of Mines (Stockwell) for S*nix, Universities of Indiana and Buffalo for linux and the University of Florida for Matlab. Links to these sites are available from the syllabus for this class.
