MATLAB
___________________________________________________________________________

MATLAB (matrix laboratory) is a numerical computing environment and fourth-generation programming language. Developed by MathWorks, MATLAB allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages, including C, C++, and Fortran.

Although MATLAB is intended primarily for numerical computing, an optional toolbox uses the MuPAD symbolic engine, allowing access to symbolic computing capabilities. An additional package, Simulink, adds graphical multi-domain simulation and Model-Based Design for dynamic and embedded systems.

In 2004, MATLAB had around one million users across industry and academia. MATLAB users come from various backgrounds of engineering, science, and economics. Among these users are academic and research institutions such as Massachusetts Institute of Technology, NASA, Max Planck Society as well as industrial enterprises such as ABB Group, Boeing, Caterpillar Inc., Ford Motor, Halliburton, Lockheed Martin, Motorola, Novartis, Pfizer, Philips, Toyota, and UniCredit Bank.


 setfocus - Set focus to objects. When starting a Matlab GUI it is normally not possible to activate the cursor in an edit object. Before you can type, you'll have to click with the mouse in the edit field. With setfocus it is possible to activate the cursor with program code by passing the object handle to setfocus. setfocus simply simulate a mouseclick in the area of the object.

ELECTRONIC AND COMMUNICATION ENGINEERING

is an engineering discipline which uses the scientific knowledge of the behavior and effects of electrons to develop components, devices, systems, or equipment (as in electron tubes, transistors, integrated circuits, and printed circuit boards) that uses electricity as part of its driving force. Both terms denote a broad engineering field that encompasses many sub fields including those that deal with power, instrumentation engineering, telecommunications, semiconductor circuit design, and many others.
