engineering. No matter what your background—be it physics, chemistry, math, or. `' x! k3 R; t; Z6 z! u c
engineering—it would behoove you to at least learn the basics of this powerful tool.& B( @+ a2 v& ]+ d/ C9 m
There are three good reasons to learn a computational mathematics tool. The first is- n) X7 O0 T6 q
that it serves as a background check for work you might be doing by hand. If you are3 y0 w( l8 U, ~7 p9 A6 b' T6 }
a student, it’s nice to have a back up that you can use to check your answers. I advise0 O2 @' Q( s" Z8 P5 k4 ?7 h0 k
that you don’t become co-dependent on a computational tool or trust it as though it$ h# c4 s* S6 K
were an Oracle. Do your work by hand when requested by your professors and just use( `2 l( F: v# ~9 a7 [# v) J
MATLAB or any other tool to check your work to make sure it’s correct.) C1 f+ R6 K, @$ y" E
The second reason is having a tool like MATLAB is priceless for generating
" L* S1 E3 P/ |1 M* Vplots and for doing numerical methods. Instead of having to go through a tedious9 ~9 G J/ G: X2 ]1 D7 A& W5 f# Q
process of plotting something by hand you can just have MATLAB generate any$ _# L5 d2 G/ d
nice plot you desire.
& O2 l* i7 j+ o! p. [Thirdly, the bottom line is that at some point in your career you will have to use

one point or another you are going to be working on a project where analytical; u7 E2 n5 x9 S& G; o9 m2 v
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
