Preface

engineering—it would behoove you to at least learn the basics of this powerful tool.! u3 Z' S, u+ z8 J( v7 ]
There are three good reasons to learn a computational mathematics tool. The first is

a student, it’s nice to have a back up that you can use to check your answers. I advise

were an Oracle. Do your work by hand when requested by your professors and just use8 S7 [5 g9 Q! ?& j4 G2 D. @9 Q
MATLAB or any other tool to check your work to make sure it’s correct.
6 s" e2 E8 D* h4 O. ?The second reason is having a tool like MATLAB is priceless for generating9 X7 O: |& h0 Z+ A5 ^; h
plots and for doing numerical methods. Instead of having to go through a tedious, S) ]0 _7 J9 o% H
process of plotting something by hand you can just have MATLAB generate any& H* F x$ p+ Y% n
nice plot you desire.

a computational mathematics tool. If you’re a professor doing theoretical work, at/ h$ z( x' \( B9 b! h2 h
one point or another you are going to be working on a project where analytical* p, A) L. ~) T2 Y" c' S0 s
solutions are not possible. If you work in industry or in a national lab, chances are, I6 J3 E) p/ ^7 C9 d; B, t
the work you’re doing can’t be done by hand and will require a numerical solution.1 x7 m" M- c2 T
MATLAB is widely used in universities, in national laboratories and at private

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
