And now that I've got things arranged to my liking let's have a look at this function. And let's put this command window right underneath the editor down here. We'll find out what that strange name means in a minute. It's one that I've got over here called noprealloc. But let's run this much slower function instead. That took, what? A little over 1,000th of a second. Let's times sum, adding up the first thousand positive numbers. Tick starts the stopwatch, tock stops it. Anyway, tick and tock work more like a stopwatch than a clock. Tell you what, go rent an old horror movie, they have lots of tick tocking clocks in them. The names are supposed to sound like a clock ticking, you know, tick, tock. You time a function with the help of two other functions called tick and tock.

I promised to tell you how to time a function. More information about these resources can be found on the Resources menu on the right. The students are encouraged to consult the eBook that this course is based on.

Students taking the course will get a MATLAB Online license free of charge for the duration of the course. 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. It is an introductory programming course that uses MATLAB to illustrate general concepts in computer science and programming. Nevertheless, this course is not a MATLAB tutorial. Hence, a solid background in MATLAB is an indispensable skill in today’s job market. 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. The problems may be relatively complex, while the MATLAB programs that solve them are relatively simple: relative, that is, to the equivalent program written in a general-purpose language, such as C++ or Java. The design of the language makes it possible to write a powerful program in a few lines. MATLAB is a special-purpose language that is an excellent choice for writing moderate-size programs that solve problems involving the manipulation of numbers. 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. This course teaches computer programming to those with little to no previous experience.
