Familarisation with MATLAB
The name MATLAB stands for matrix laboratory produced by Mathworks Inc.,USA.It is a matrix based powerful software package for scientific and engineering numerical computation and visualization. Complex numerical problems can be solved in a fraction of the time .It provides an interactive environment with hundreds of built-in functions for technical computations, graphics and animation. In addition to built in functions, user can create his own functions.
MATLAB has three basic windows namely-command window, graphics window and edit window. Command window is characterized by the prompt ‘>>’ .All commands and the ready to run program filename can be typed here. Graphics window gives the display of the figures. Edit window is to create program files with an extension .m.
