Preface

* h* L2 g3 U" S4 q5 oengineering—it would behoove you to at least learn the basics of this powerful tool.
6 n; d/ v! g3 w* s9 }' M( n6 v! mThere are three good reasons to learn a computational mathematics tool. The first is* C3 E; L7 C, k
that it serves as a background check for work you might be doing by hand. If you are8 V T# ^- F; z" A
a student, it’s nice to have a back up that you can use to check your answers. I advise
, f; T' D4 f" E6 ^3 Y2 D5 ?( ?that you don’t become co-dependent on a computational tool or trust it as though it( O. v! b& R+ K/ G* S9 f
were an Oracle. Do your work by hand when requested by your professors and just use3 z4 U3 U: v" t! G5 l) B0 \: S
MATLAB or any other tool to check your work to make sure it’s correct.
W2 x7 b$ E8 N. u5 x6 s. k o9 _The second reason is having a tool like MATLAB is priceless for generating4 l0 ]; z6 _% `3 r" j
plots and for doing numerical methods. Instead of having to go through a tedious2 c: T" x) o/ ^+ ^
process of plotting something by hand you can just have MATLAB generate any
. ] e- ^$ X2 B, J$ u/ f( J* ?nice plot you desire.
; B8 y' s8 c- P& @, |, T Z) G$ D7 sThirdly, the bottom line is that at some point in your career you will have to use0 g5 ]' `, P& E9 k! C+ ]
a computational mathematics tool. If you’re a professor doing theoretical work, at2 T- z& o5 ?8 Q# I5 U
one point or another you are going to be working on a project where analytical
5 R* P2 ?7 p! Ksolutions are not possible. If you work in industry or in a national lab, chances are
* e/ o& K6 U5 U8 P6 mthe work you’re doing can’t be done by hand and will require a numerical solution.1 y& K: |; G! h9 i+ r/ a
MATLAB is widely used in universities, in national laboratories and at private
7 F: z! X: x% ]companies. Knowing MATLAB will definitely be a plus on your resume.
: D$ Y7 b9 y G. p z& |Now a word about this particular book. This book is aimed squarely at the MATLAB& O6 o$ z ~0 i9 i1 ^
beginner. The purpose is not to wow experts with complicated solutions built with7 P3 S9 I9 l( ?! @
MATLAB. Rather, the purpose of this book is to introduce a person new to MATLAB
# X- A8 }, y+ X5 C& ]to the world of computational mathematics. The approach taken here is to set about4 p- E" P1 L$ w/ \
learning how to use MATLAB to do some basic things-plot functions, solve algebraic
; d, j L9 t8 E$ E7 z- z+ q. Dequations, compute integrals and solve differential equations for example. So the W9 K# {. j0 M% t* P
examples we present in this book are going to be ** and aimed at the novice. If
' ]& v: `* s e+ Myou have never touched MATLAB before or are having lot’s of trouble with it, this
. a+ }4 a# z' D( L# |2 l& Z& qbook will help you build a basic skill set that can be used to master it. The book is a4 X4 S4 d) f' O! u/ h- e
stepping stone to mastery and nothing more. |
