MATLAB is one of the most widely used computational tools in science and/ _$ g& G5 g* |( U6 Z/ Q8 x' R
engineering. No matter what your background—be it physics, chemistry, math, or
4 Y8 I0 W1 k# b c; i* c9 H- |% Fengineering—it would behoove you to at least learn the basics of this powerful tool.
; E; f* f- |4 E6 BThere are three good reasons to learn a computational mathematics tool. The first is+ l' F. c' ?2 _' _$ P
that it serves as a background check for work you might be doing by hand. If you are5 V B- ]+ r, o
a student, it’s nice to have a back up that you can use to check your answers. I advise& s& P" d* D3 o, O6 h1 e
that you don’t become co-dependent on a computational tool or trust it as though it- }$ |1 T9 ]0 Q' E. u6 D
were an Oracle. Do your work by hand when requested by your professors and just use
: i J% w( V# T' fMATLAB or any other tool to check your work to make sure it’s correct.% P' ~$ A9 o/ I+ h) C' @
The second reason is having a tool like MATLAB is priceless for generating
7 [* Z1 }# ]0 `) ^6 E3 N9 v0 ~, L+ jplots and for doing numerical methods. Instead of having to go through a tedious
, _3 V! j4 S ?3 H+ _process of plotting something by hand you can just have MATLAB generate any. V% ^% f! X% h& _
nice plot you desire.
5 Q9 C3 z6 U; C. VThirdly, the bottom line is that at some point in your career you will have to use
, N9 N' f2 }2 m6 ~ j6 ka computational mathematics tool. If you’re a professor doing theoretical work, at) }4 `( v9 T. x( u2 H; m! Z" M0 X
one point or another you are going to be working on a project where analytical6 f* N* k; U4 `: ~ s1 k
solutions are not possible. If you work in industry or in a national lab, chances are$ T6 q* V! o3 V3 | D
the work you’re doing can’t be done by hand and will require a numerical solution.

Now a word about this particular book. This book is aimed squarely at the MATLAB( `7 p% ~6 h9 _
beginner. The purpose is not to wow experts with complicated solutions built with: [ v0 @& l$ Y' @
MATLAB. Rather, the purpose of this book is to introduce a person new to MATLAB
% M+ a" b; k' Lto the world of computational mathematics. The approach taken here is to set about+ s3 G* w. a6 m; W* f2 g. m# X, `( f
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
