MATLAB is one of the most widely used computational tools in science and! I' \/ g D4 O" _
engineering. No matter what your background—be it physics, chemistry, math, or
3 C f: T( H; h6 s% y4 _1 {% Tengineering—it would behoove you to at least learn the basics of this powerful tool.
, J: _* ^ X+ { H. tThere are three good reasons to learn a computational mathematics tool. The first is
8 \) \7 E9 P t* Sthat it serves as a background check for work you might be doing by hand. If you are
0 o7 y8 L2 G+ M* G+ Z2 l& d6 t1 p8 }a student, it’s nice to have a back up that you can use to check your answers. I advise. e1 `. K: Q2 Q2 }, O) E
that you don’t become co-dependent on a computational tool or trust it as though it. A3 a5 d4 H6 l8 k* o7 H
were an Oracle. Do your work by hand when requested by your professors and just use2 S$ w. N' E3 l9 T2 I
MATLAB or any other tool to check your work to make sure it’s correct.5 U. j4 W3 s" C# ~. [+ Y
The second reason is having a tool like MATLAB is priceless for generating
: d6 d& E1 d5 F+ Eplots and for doing numerical methods. Instead of having to go through a tedious7 u% u& \0 X; D2 d& ?! W) h
process of plotting something by hand you can just have MATLAB generate any
5 f+ }8 r% i8 j: Inice plot you desire.( H0 ?! @; [ B6 j% ]3 ~, B! Z
Thirdly, the bottom line is that at some point in your career you will have to use
5 n4 c# M& Y8 ^0 \7 La computational mathematics tool. If you’re a professor doing theoretical work, at+ x! D# V, f1 j$ c( c$ o
one point or another you are going to be working on a project where analytical

. \1 s% `( i! j3 e! c0 Sthe work you’re doing can’t be done by hand and will require a numerical solution.; [: j1 d: q" }: J
MATLAB is widely used in universities, in national laboratories and at private9 g4 _9 B( ]* m' ^% {% r
companies. Knowing MATLAB will definitely be a plus on your resume.& U& j) Q4 r6 r3 a1 J
Now a word about this particular book. This book is aimed squarely at the MATLAB
3 H& W% o1 `) c4 o. Dbeginner. The purpose is not to wow experts with complicated solutions built with. _ e2 k5 D+ C
MATLAB. Rather, the purpose of this book is to introduce a person new to MATLAB
* b0 S$ ^% p/ j& p( }to the world of computational mathematics. The approach taken here is to set about7 r I( }* A' j& M1 I
learning how to use MATLAB to do some basic things-plot functions, solve algebraic# b! A" P& I8 A: [2 M
equations, compute integrals and solve differential equations for example. So the
k/ R& `( I) bexamples we present in this book are going to be ** and aimed at the novice. If
# _4 a/ d+ T' ]( ?( Yyou have never touched MATLAB before or are having lot’s of trouble with it, this$ E8 S9 ]# w5 R: s
book will help you build a basic skill set that can be used to master it. The book is a
