  1. Chapter 1:Brief Overview of MATLAB MATLAB for Scientist and Engineers Using Symbolic Toolbox

  2. You are going to • Exposeyourself to the history of MATLAB, • See what MATLAB provides, • Look at a symbolic math example.

  3. Old History of MATLAB • 1967: "Computer solution of linear algebraic equations", Forsythe and Moler • 1976: "Matrix Eigensystem Routines, EISPACK Guide" in FORTRAN • 1976~9: "LINPACK" in FORTRAN • 1977~: "MATLAB Environment", Cleve Moler • 1971: "Handbook for automatic computations" in ALGOL, • J. H. Wilkinson et. al. Cleve Moler (1939~) J.H.Wilkinson, UK (1919~1986) • 1979: "Numerical analysis" lecture at Stanford, • met with Jack Little, then an engineering student • 1984: MathWorks founded by Jack and Moler Jack Little
