1- Introduction:
MATLAB is a powerful computing system for handling the calculations
involved in scientific and engineering problems. The name MATLAB
stands for MATrix LABoratory, because the system was designed to make
matrix computations particularly easy. One of the many things you will like
about MATLAB (and which distinguishes it from many other computer
programming systems, such as C++ and Java) is that you can use it
interactively. This means you type some commands at the special
MATLAB prompt, and get the answers immediately. The problems solved
in this way can be very simple, like finding a square root, or they can be
much more complicated, like finding the solution to a system of differential
equations. For many technical problems you have to enter only one or two
commands, and you get the answers at once. MATLAB does most of the
work for you.
