MATLAB - Environment


Try it Option Online

You really do not need to set up your own environment to start learning MATLAB/Octave programming language. Reason is very simple, we already have set up the Octave environment online, so that you can execute all the available examples online at the same time when you are doing your theory work. This gives you confidence in what you are reading and to check the result with different options. Feel free to modify any example and execute it online.

Try following example using Try it option available at the top right corner of the below sample code box:

x = [1 2 3 4 5 6 7 8 9 10];
y1 = [.16 .08 .04 .02 .013 .007 .004 .002 .001 .0008 ];
y2 = [.16 .07 .03 .01 .008 .003 .0008 .0003 .00007 .00002 ];

title('Plot title');
xlabel('X Axis');
ylabel('Y Axis');
print -deps graph.eps

For most of the examples given in this tutorial, you will find Try it option, so just make use of it and enjoy your learning.

Local Environment Setup

If you are still willing to set up your environment, let me tell you a secret, setting up MATLAB environment is a matter of few clicks. However, you need to download the installer from here:

MathWorks provides the licensed product, a trial version and a student version as well. You need to log into the site and wait a little for their approval.

Once you get the download link, as I said, it is a matter of few clicks:

Understanding the MATLAB Environment:

You can launch MATLAB development IDE from the icon created on your desktop. The main working window in MATLAB is called the desktop. When you start MATLAB, the desktop appears in its default layout:
