Cell arrays can be indexed by both curly braces and smooth parentheses. With parentheses, c k is another cell array containing the specified cells. Think of a collection of mailboxes. This script for creating a grade book for a small class shows structures and dot notation at work. Creating classes can simplify programming tasks that involve specialized data structures or large numbers of functions that interact with particular kinds of data.

MATLAB classes support function and operator overloading, controlled access to properties and methods, reference and value semantics, and events and listeners. Over time we added separate windows for graphics, editing, and other tools. Two specific features that have had the biggest impact are the desktop and the Live Editor. A file viewer and a command history window can also be included in personalized layouts. The toolbox supports coarse-grained, distributed memory parallelism by running many MATLAB workers on several machines in a cluster or on many cores in a single machine.

MPI is used for the underlying message passing. By far the most popular feature of the toolbox is the parallel for loop command, parfor. The toolbox also supports fine-grained, shared memory parallelism in attached graphics processing units GPUs. Here, the gpuArray array gets things started.

As of release a, there are 63 of them:. It is a living ecosystem supporting all aspects of technical computing. We will continue to strengthen existing features as we carefully add new ones. The Internet is popular among the students. Students search more and more for information on the Internet.

Studies show that many students consider the Internet as a great source of information and using it during learning process. The Internet is full of e-learning projects, documents, presentations and multimedia content that students may find useful for their learning process Foltin b , 2 c.

It is necessary that all our contents for courses are available online as well. Courses can be also supported with custom video tutorials where topics are explained and shown. Mathworks also provide online content like the documentation, webinars and events on their official web site. Conferences are also good events for students to exchange their knowledge among each other MathWorks a, b, c.

Learning and teaching process is often high cost. Free software and open source applications are possible solution Foltin et al. In this chapter we will describe possibilities for an introductory Matlab course.

We will show how to divide lectures and practices into several topics necessary and helpful for the students. Weekly task evaluations are proposed to motivate students to achieve better results.

We will described how to find an interesting resources for the course or how to create own one. Collaboration among students is described within the Internet with the Facebook, articles or forums.

Over all we focused on the educational use of Matlab, concepts for lecturers and the course improvements. Matlab is a very powerful tool for technical computing and simulation.

It is time saving tool for high performance computations. Matlab is optimized for this kind of tasks. It supports us when we lack of real world system in the education. Matlab contains many add-ons that are very useful in many fields of science. Matlab usage is a very popular in many science projects, bachelor, master and dissertation theses in the university environment.

The basic Matlab course was established at the Faculty of Electrical Engineering and Information Technology in Bratislava to teach students to use Matlab and its add-ons. Matlab is a basic tool for every student at our faculty. We try to move this course into the first year of study for this reason.

The knowledge, which students take from this course is a very useful in the other technical courses. As we mentioned before at the Faculty of Electrical Engineering and Information Technology Bratislava there is Matlab used in many mathematical and technical courses. Students use Matlab for their computations and solutions in their bachelor, diploma or dissertation theses. Matlab course is introductory course to Matlab, Simulink and Matlab toolboxes.

The faculty has two terms per year. Each term lasts twelve weeks. Course can be taken in second term of the first year of undergraduate study. It consists of one lecture minutes and practice minutes per week. The lectures are not compulsory, but practices are. Count of the attendance at lectures is more than a half of all students. The lectures are combination of explanation of the current topic, solving of basic tasks and discussion. All of tasks are solved directly on the computer using Matlab.

The students are allowed to see how to solve the concrete problem and can write the notes into their hand-out. The full preprint of lecture is available a week ahead on the web pages of the course. The students can print this hand-out before the lecture. The hand-out with notes are useful source of the information for the practices. For this reason there are usually students who attend the lectures more successful than students who do not have the notes from the lectures.

The aim of the Matlab course is to introduce students to the Matlab, to learn basic principles, syntax and solutions of some common problems. We focus on the most common problems which students may use in their future study or on the others courses. We cover these topics:. As you can see, there are many topics for just one course. But with the lecture time we just cover a simple introduction to these topics. That is not a big problem because they will have detailed courses for most of the mentioned topics in the future.

The main idea is to show basic principles and solutions to students that Matlab could provide. They can extend knowledge gained from the Matlab course on the other courses.

The practices are related to the lectures. Students are solving some problems similar to the topic on the actual lecture. Problem is at the first solved verbally and using the board. Students then try to find out solutions in the Matlab environment. This is a time for notes from the lecture.

Practices are set up in the way that students have not much time to learn the topic on the exercise and they have to always come prepared. Every student has his computer and work alone. Students can also use their own notebooks. These facts improve the environment in the class. There are two lessons that take hour and forty minutes together.

Teacher checks and rate every students work about ten minutes before end of the practice. The tasks are prepared for students that they should finish the given tasks before hour and half without problem. Many of students can solve given problems successfully in time. Although we teach Matlab course at university the question is if we could find usage of Matlab at lower levels of education.

The answer to this question is of course yes. We think that Matlab is great supportive program for secondary schools teachers and it should be used in mathematics and physics courses. For example let us look at this two equations:. With given acceleration due to gravity g we can compute distance x and height y of objects trajectory at certain time t.

In the next figure you can see trajectories for different angles with same start point, speed and gravity. In the most of the secondary schools teachers and students compute results on the table or the paper.

Matlab can be used to visualize different trajectories in just few lines of code for better understanding and imagination of the problem. With additional commands we could animate whole movement. This is one of the examples how to use Matlab in secondary schools physics classes. Another question is if Matlab should be considered only as a supporting program for the teachers or if students should also learned know how to create own scripts and programs. We think that we should consider both.

Benefits of the first part of the question were answered with our example before. Writing Matlab scripts and programs should not be a problem for the students also because of its simplicity. We think that for students it would be also interesting. They would also learn some basic concepts of algorithm writing. Trajectories of thrown object. In previous chapter we generally talked about the Matlab practices and lectures at the universities.

We briefly showed how you could use the Matlab benefits in secondary schools also. This chapter will discus topics suitable for basic Matlab course. We divided topics into three categories. Essential topics are parts of Matlab that every student should know because they provide strong platform for advanced topics and other Matlab toolboxes.

Advanced topics should cover additional parts of the Matlab necessary for later student courses. We will describe topics that we cover in our course but other interesting parts of the Matlab suitable for other study programs are described in other interesting topics.

With Matlab core components come several add-ons as well. It is necessary to know all about basic Matlab concepts before we start to use specializes toolboxes suitable for our needs. In our opinion the essential topic for advanced Matlab users should be Matlab basics, graphics, Graphical User Interface and Simulink.

Next we will talk in the detail about each of them and on what we should focus at most. Understanding of the Matlab basic principles is key to be successful advanced Matlab user. Students should know how to use Matlab windows Command Window, Workspace, History and the benefits of each of them.

Effective usage of Matlab help system is also necessary to solve Matlab warnings and errors. It is our choice if we use fast help command or Matlab Product help where user can find detailed information. Basic computations can be made in the Command Window through statements or in scripts M-files for example area of the circle. For additional support we can use the built-in Matlab functions for complex numbers or trigonometry functions.

What makes Matlab powerful tool are vectors and matrices. There are several ways to create and manipulate them. Working with indexes of matrix is a very important and challenging parts in the Matlab for students, even harder with indexes range. Programing in the Matlab with functions, loops or conditions is one of the highlights of Matlab basics. In our course we are creating simple sorting algorithms. Students must then use almost every part of Matlab basics that we mentioned in this section.

We are also teaching advanced data types — structures and cells. Data types are often used as types for output or input arguments to several Matlab functions. Functions and scripts provide sets of commands necessary for computing output data. Reading plain data is hard and we need some mechanism to represent them. Matlab contains several plotting commands for 2D and 3D figures. In 3D plotting we need to create grid for 3D space through meshgrid command.

Some students have a hard time to understand this concept. Changing plot properties is another important knowledge. We must create handler to plot and using get and set commands we can change line colour or type. We can also use standard Matlab handles like current axis gca , current figure gcf or current object gco. Matlab enable creating graphical user interface. With objects like buttons, labels, inputs or check box we can create interactive experience for users with no prior Matlab knowledge.
