Preface- z _( ?; W# L6 y) Q& e
MATLAB is one of the most widely used computational tools in science and

+ B! r$ U/ S4 k. E! ?" bengineering—it would behoove you to at least learn the basics of this powerful tool.
2 g4 V3 I% Q+ m& l" ^/ s/ f5 i$ kThere are three good reasons to learn a computational mathematics tool. The first is- J" c/ U7 V* [. P
that it serves as a background check for work you might be doing by hand. If you are
' K5 G# q4 R3 fa student, it’s nice to have a back up that you can use to check your answers. I advise
1 y# x; J- H9 B2 `that you don’t become co-dependent on a computational tool or trust it as though it
0 F3 g# _8 O' Xwere an Oracle. Do your work by hand when requested by your professors and just use6 V r$ c; P: S6 ?/ \8 C3 P
MATLAB or any other tool to check your work to make sure it’s correct.
5 {0 e+ Q: j: C+ {The second reason is having a tool like MATLAB is priceless for generating
% [1 S- _, U) `plots and for doing numerical methods. Instead of having to go through a tedious& h% N+ { x0 Y. u; F# B; P; j+ S9 s7 x
process of plotting something by hand you can just have MATLAB generate any

a computational mathematics tool. If you’re a professor doing theoretical work, at

solutions are not possible. If you work in industry or in a national lab, chances are

Now a word about this particular book. This book is aimed squarely at the MATLAB; Z& Z; H! e; `7 j% L L
beginner. The purpose is not to wow experts with complicated solutions built with6 t! P/ Q+ K* u
MATLAB. Rather, the purpose of this book is to introduce a person new to MATLAB6 \' v* ]9 D2 s% g7 B3 i) S. H8 `
to the world of computational mathematics. The approach taken here is to set about" [( i" K$ m3 s
learning how to use MATLAB to do some basic things-plot functions, solve algebraic
: ^2 v& s$ r% J! F @9 P. G x# zequations, compute integrals and solve differential equations for example. So the( I6 N: i$ L6 \
examples we present in this book are going to be ** and aimed at the novice. If$ F7 ]$ l( x3 N x
you have never touched MATLAB before or are having lot’s of trouble with it, this8 R' x7 z4 J0 r* j
book will help you build a basic skill set that can be used to master it. The book is a# L. U. b; s" h- c& Q- |# V
stepping stone to mastery and nothing more. |
