! s0 y6 W3 k# i! @4 D) f" jMATLAB 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.
) C8 P" Z. _5 bThere are three good reasons to learn a computational mathematics tool. The first is
1 R) y. X1 o' | gthat it serves as a background check for work you might be doing by hand. If you are
# s0 }" \/ q9 [% U: K( [a student, it’s nice to have a back up that you can use to check your answers. I advise& r$ R, P' V" l3 A' r
that you don’t become co-dependent on a computational tool or trust it as though it7 x5 [2 I5 j% h7 W
were an Oracle. Do your work by hand when requested by your professors and just use9 `6 t$ U# x! O9 f8 C2 N
MATLAB or any other tool to check your work to make sure it’s correct.
, y' H k+ D' |& u! B+ y5 h2 pThe second reason is having a tool like MATLAB is priceless for generating% F G1 T3 b! U# \; v
plots and for doing numerical methods. Instead of having to go through a tedious
& N0 `3 P' V+ n/ y9 ]process of plotting something by hand you can just have MATLAB generate any
% R8 _/ \" \% V, i" n1 vnice plot you desire.
7 g! u0 l. Q b& e1 @7 r \, ] i0 n( EThirdly, the bottom line is that at some point in your career you will have to use
# F/ [0 i& J; u* Z' h8 n. xa computational mathematics tool. If you’re a professor doing theoretical work, at
. u3 \& W. Y( g cone point or another you are going to be working on a project where analytical
3 P$ q3 s- \3 nsolutions are not possible. If you work in industry or in a national lab, chances are
9 v4 u3 j+ C/ `7 A- [- s$ Cthe work you’re doing can’t be done by hand and will require a numerical solution.
$ |- P, `8 C) SMATLAB is widely used in universities, in national laboratories and at private" @; ]' v# i# y
companies. Knowing MATLAB will definitely be a plus on your resume.2 [, W, w$ s, d: u
Now a word about this particular book. This book is aimed squarely at the MATLAB
1 T4 E: q G8 J% w3 G. n" zbeginner. The purpose is not to wow experts with complicated solutions built with% ]- @: o# W3 ^: W7 X
MATLAB. Rather, the purpose of this book is to introduce a person new to MATLAB
2 X* A( w& |* c( X/ l* V6 R( H; y6 Zto the world of computational mathematics. The approach taken here is to set about! C# S; [) F! p2 |9 a% v
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/ @+ z6 F$ h6 c, Q0 I4 U- X
you have never touched MATLAB before or are having lot’s of trouble with it, this( v' B0 R/ i- F2 h2 G! v
book will help you build a basic skill set that can be used to master it. The book is a2 T ?9 O+ M9 l6 X: p) O$ Z! G
stepping stone to mastery and nothing more. |
