[1 V& I% G6 jPreface
9 E. G4 j1 A0 b% m7 {* bMATLAB is one of the most widely used computational tools in science and
5 W* e- y" E" P6 P0 g5 [engineering. No matter what your background—be it physics, chemistry, math, or( m" E* w% H3 T7 l6 ^6 h
engineering—it would behoove you to at least learn the basics of this powerful tool.. M3 s# u% o/ }+ H/ z$ l# p, G, B
There are three good reasons to learn a computational mathematics tool. The first is( t8 c3 \& \" x U0 d& R- @: H
that it serves as a background check for work you might be doing by hand. If you are
7 p) \) K" @) d; I% Z7 J2 Ca student, it’s nice to have a back up that you can use to check your answers. I advise$ }% R0 E. B. B, x3 _3 w
that you don’t become co-dependent on a computational tool or trust it as though it
( P4 m' _4 I, kwere an Oracle. Do your work by hand when requested by your professors and just use
# q) t& Z% z2 p7 }4 _7 m- V, R5 nMATLAB or any other tool to check your work to make sure it’s correct.

plots and for doing numerical methods. Instead of having to go through a tedious! }1 Y. z; n. K2 F, u* U) r
process of plotting something by hand you can just have MATLAB generate any

Thirdly, the bottom line is that at some point in your career you will have to use! Q/ {3 ?: y& R1 |
a computational mathematics tool. If you’re a professor doing theoretical work, at' u- @6 ~& j G" W; b
one point or another you are going to be working on a project where analytical0 @! k& J5 K6 d- ^+ r+ M
solutions are not possible. If you work in industry or in a national lab, chances are& x5 Q2 f1 R, V+ W; r p8 U
the work you’re doing can’t be done by hand and will require a numerical solution.2 w: M! M. M& L* R1 I \
MATLAB is widely used in universities, in national laboratories and at private
: u) M& `7 ^" o( e/ k" B# [companies. Knowing MATLAB will definitely be a plus on your resume.
8 W4 o( B8 Q" x, M) p% j6 HNow 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* U$ Y! [2 ~+ u8 u" v
you have never touched MATLAB before or are having lot’s of trouble with it, this
" P u/ n/ I3 _book will help you build a basic skill set that can be used to master it. The book is a
