It uses the programming system and language called MATLAB to do so because it is easy to learn, versatile and very useful for engineers and other professionals. MATLAB is a special-purpose language that is an excellent choice for writing moderate-size programs that solve problems involving the manipulation of numbers.
The design of the language makes it possible to write a powerful program in a few lines. As a result, MATLAB is being used in a wide variety of domains from the natural sciences, through all disciplines of engineering, to finance, and beyond, and it is heavily used in industry.
Nevertheless, this course is not a MATLAB tutorial. It is an introductory programming course that uses MATLAB to illustrate general concepts in computer science and programming. Students who successfully complete this course will become familiar with general concepts in computer science, gain an understanding of the general concepts of programming, and obtain a solid foundation in the use of MATLAB.

There are a lot of them. But for this course we've decided to use a programming language that youmay not have heard of.
MATLAB is very easy to use and to learn. And at the same time, it's very powerful. It's nine weeks long, including eight weeks of video lectures, andone week for a final homework submission. Do the quizzes and the homeworks,then by the end of the ninth week you'll be able to program a computer.
