Preface P$ Q3 o# r. _. M
MATLAB is one of the most widely used computational tools in science and

engineering—it would behoove you to at least learn the basics of this powerful tool.
& K+ G: h; k* L0 w8 kThere are three good reasons to learn a computational mathematics tool. The first is
% L8 T& b: r6 w! L, r+ ethat it serves as a background check for work you might be doing by hand. If you are
2 f; t2 `/ G' Ya student, it’s nice to have a back up that you can use to check your answers. I advise0 _* F1 x! \$ i( L
that you don’t become co-dependent on a computational tool or trust it as though it4 o: X0 h* w+ Y. G, O% ]3 i
were an Oracle. Do your work by hand when requested by your professors and just use
, t$ d1 u1 ]4 P; @MATLAB or any other tool to check your work to make sure it’s correct.
4 [2 Y9 b0 j! l8 ?: y' x, TThe second reason is having a tool like MATLAB is priceless for generating6 y& Q& D% i9 ]8 b9 l9 T
plots and for doing numerical methods. Instead of having to go through a tedious

Thirdly, the bottom line is that at some point in your career you will have to use

one point or another you are going to be working on a project where analytical

Now a word about this particular book. This book is aimed squarely at the MATLAB

MATLAB. Rather, the purpose of this book is to introduce a person new to MATLAB

learning how to use MATLAB to do some basic things-plot functions, solve algebraic

examples we present in this book are going to be ** and aimed at the novice. If

stepping stone to mastery and nothing more. |
