INTRODUCTION:

MATLAB stands for MATRIX LABORATORY. MATLAB is a high-performancelanguage for technical computing. It integrates computation, isuali!ation, andprogramming enironment. MATLAB is a modern programming language enironment"

it has sophisticated data structures, contains #uilt-in editing and de#ugging tools, andsupports o#$ect-oriented programming. These factors ma%e MATLAB an e&cellent toolfor teaching and research.

MATLAB is an interactive system whose basic data element is an arraythat does not require dimensioning.

It has powerful built-in routines that enable a very wide variety of computations. ItAlso has easy to use graphics commands that mae the visuali!ation of results immediately available. "peci#c applications are collected in pacagesreferred to as toolbo$. There are toolbo$es for signal processing% symboliccomputation% control theory% simulation% optimi!ation% and several other

#elds of applied science and engineering.
