: ]9 i2 A+ X9 n% ]MATLAB 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.
/ E* m/ Y+ R/ v- ~9 E2 C/ lThere are three good reasons to learn a computational mathematics tool. The first is, I5 \$ ^: \5 m, s1 V" O
that it serves as a background check for work you might be doing by hand. If you are0 A9 V2 o+ V( b# J2 O' r4 g
a student, it’s nice to have a back up that you can use to check your answers. I advise
1 G5 [' K; t1 m2 pthat you don’t become co-dependent on a computational tool or trust it as though it

The second reason is having a tool like MATLAB is priceless for generating6 }; t& I, F1 n6 Q# {+ L7 U
plots and for doing numerical methods. Instead of having to go through a tedious, y: e+ | R" B% z) g" N
process of plotting something by hand you can just have MATLAB generate any

Thirdly, the bottom line is that at some point in your career you will have to use

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

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 MATLAB7 ]! h/ ]; \( t6 y9 a+ Y
beginner. The purpose is not to wow experts with complicated solutions built with0 m3 y1 u- b4 E1 w7 L" X9 r- v
MATLAB. Rather, the purpose of this book is to introduce a person new to MATLAB! _3 P9 x2 [5 `: O& Z/ G5 k! D
to the world of computational mathematics. The approach taken here is to set about: K* ~. u# n& j2 o
