( `# G# v+ \& o0 w9 s* gMATLAB is one of the most widely used computational tools in science and; |/ r2 s& c$ l- u8 D
engineering. No matter what your background—be it physics, chemistry, math, or
5 f1 n7 @( T ]2 Sengineering—it would behoove you to at least learn the basics of this powerful tool.4 r5 ^- y; Z; D/ i9 D
There are three good reasons to learn a computational mathematics tool. The first is
2 I1 S+ L1 y. }0 Z9 R ethat it serves as a background check for work you might be doing by hand. If you are
+ v. S3 O! I8 k% m9 o, ~0 B: R1 }a student, it’s nice to have a back up that you can use to check your answers. I advise
: S% I" @9 A- ]1 jthat you don’t become co-dependent on a computational tool or trust it as though it6 a1 ^7 }; a% W1 Y
were an Oracle. Do your work by hand when requested by your professors and just use
1 Y8 O: K4 g7 \/ n- T; h7 }$ k qMATLAB or any other tool to check your work to make sure it’s correct.& F* U% b0 S4 I) }
The second reason is having a tool like MATLAB is priceless for generating7 e; z2 |" u) _ q+ E
plots and for doing numerical methods. Instead of having to go through a tedious
- b0 G. P0 V- p. V- ?process of plotting something by hand you can just have MATLAB generate any# G- O$ P* S* l0 h5 w
nice plot you desire.# _$ g9 }- f3 ~
Thirdly, the bottom line is that at some point in your career you will have to use
0 O- n! h5 S+ |/ m1 la computational mathematics tool. If you’re a professor doing theoretical work, at
' h5 O$ w- W( `one point or another you are going to be working on a project where analytical

MATLAB is widely used in universities, in national laboratories and at private

Now a word about this particular book. This book is aimed squarely at the MATLAB
( z' G- s1 L3 k/ A* t: ` rbeginner. The purpose is not to wow experts with complicated solutions built with
2 M) b0 w2 g# s9 f" |0 w9 ~MATLAB. Rather, the purpose of this book is to introduce a person new to MATLAB8 }* T' z# y6 k% r! D
to the world of computational mathematics. The approach taken here is to set about
4 y( B3 v. Z9 A& xlearning how to use MATLAB to do some basic things-plot functions, solve algebraic
: q8 A9 P) O& g% ]6 x3 ]: Fequations, compute integrals and solve differential equations for example. So the! ^. H' K2 ~: b
examples we present in this book are going to be ** and aimed at the novice. If
* w1 l! z$ }: b) A' W G( _you have never touched MATLAB before or are having lot’s of trouble with it, this
/ s% Y6 ^# R& {, k' [5 ?book will help you build a basic skill set that can be used to master it. The book is a: s4 P! P8 c) t U
stepping stone to mastery and nothing more. |
