There are three good reasons to learn a computational mathematics tool. The first is" q0 a. y2 B( R P: k
that it serves as a background check for work you might be doing by hand. If you are
1 c4 B6 v) o" Q; p: c9 C: la student, it’s nice to have a back up that you can use to check your answers. I advise
& t V9 h& e# u) _% K4 kthat you don’t become co-dependent on a computational tool or trust it as though it, z6 h1 {# W& ?0 q( S
were an Oracle. Do your work by hand when requested by your professors and just use, A& G4 f# ]; b( P4 U
MATLAB or any other tool to check your work to make sure it’s correct.
( a' ]9 W/ X( m% y' x2 j T" LThe second reason is having a tool like MATLAB is priceless for generating
