MATLAB
1 is an interactive system for numerical computation. Numerical analyst Cleve Moler wrote the initial Fortran version of MATLAB in the late 1970s as a teaching aid. It became popular for both teaching and research and evolved into a commercial software package written in C. For many years now, MATLAB has been widely used in universities and industry.
MATLAB has several advantages over more traditional means of numerical computing -e.g., writing Fortran or C programs and calling numerical libraries
It allows quick and easy coding in a very high-level language
Data structures require minimal attention; in particular, arrays need not be declared before rst use
An interactive interface allows rapid experimentation and easy debugging
High-quality graphics and visualization facilities are available
MATLAB M- les are completely portable across a wide range of platforms
Toolboxes can be added to extend the system, giving, for example, specialized signal processing facilities and a symbolic manipulation capability
A wide range of user-contributed M- les is freely available on the Internet
