Preface
& H. w7 ]/ T) N# Z! cMATLAB 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./ T2 Y0 Z( s! O
There are three good reasons to learn a computational mathematics tool. The first is
1 S: b# Q1 v8 t9 ^' ~+ Tthat it serves as a background check for work you might be doing by hand. If you are
$ L& d$ {* m% _# wa student, it’s nice to have a back up that you can use to check your answers. I advise/ `7 V$ F8 C1 [- J# h
that you don’t become co-dependent on a computational tool or trust it as though it2 ` q& n- U X* p
were an Oracle. Do your work by hand when requested by your professors and just use) w I, N/ \7 ?+ Y7 i
MATLAB or any other tool to check your work to make sure it’s correct.
/ c% Y1 ~2 ^/ ~" e( @2 Z3 b4 lThe second reason is having a tool like MATLAB is priceless for generating# \2 z1 w+ W% Z4 _5 M% v
plots and for doing numerical methods. Instead of having to go through a tedious2 P# J8 w% x. P5 W
process of plotting something by hand you can just have MATLAB generate any6 U$ M9 r# z) S% N# P& v
nice plot you desire.
- N" {& W# F) Y0 r. ^: {Thirdly, the bottom line is that at some point in your career you will have to use
5 A/ j( v( o0 n( {6 {a computational mathematics tool. If you’re a professor doing theoretical work, at3 A) D8 n, u H: d: `) y
one point or another you are going to be working on a project where analytical* o. B. t( b4 R! R3 c
solutions are not possible. If you work in industry or in a national lab, chances are
: e3 F( y4 Y% G, T' \! l$ sthe work you’re doing can’t be done by hand and will require a numerical solution.& J4 P! y/ }: N0 L, u# l
MATLAB is widely used in universities, in national laboratories and at private
# T' e1 j/ f+ m/ W) G# k$ V) ]companies. Knowing MATLAB will definitely be a plus on your resume.4 O+ Z$ N" j' \3 n( E$ V# H( B
Now a word about this particular book. This book is aimed squarely at the MATLAB
1 ^0 T- B/ u1 D) `- cbeginner. The purpose is not to wow experts with complicated solutions built with+ \5 w J% Z3 V% n$ L
MATLAB. Rather, the purpose of this book is to introduce a person new to MATLAB% ~- t% P7 P' ^0 V3 r
to the world of computational mathematics. The approach taken here is to set about
+ f; _( v: z5 Olearning how to use MATLAB to do some basic things-plot functions, solve algebraic
! g* [) ~. ~) F# d+ Eequations, compute integrals and solve differential equations for example. So the
* d' K# _* k2 t. Hexamples we present in this book are going to be ** and aimed at the novice. If
. O$ L+ M- c% \* e6 \you have never touched MATLAB before or are having lot’s of trouble with it, this+ a3 x$ L+ y! p
book will help you build a basic skill set that can be used to master it. The book is a
