WHY MATLAB Easy of use.

MATLAB is an interactive system whose basic data element

is an array that does not require dimensioning.

MATLAB is high performance language for technical

computing.

It provides various Toolboxes ex-DSP,IP,FUZZY Logic etc.

It also used to create GUI.

More than 500 mathematical & Engineering functions.

MATLAB code & data formats are Platform Independent.

MATLAB programs can be converted to C/C++.
