The editor

A very important tool in MATLAB, besides the default ones you see when first opening the environment, is the editor. The editor can be invoked in various ways, depending on what you want to accomplish. The three basic ways are:

  • Click on the New Script icon on the HOME tab
  • Click on the New icon on the HOME tab and then click on either one of the first four choices: Script, Function, Example, or Class
  • Click on the Open icon on the HOME tab and then either search for a file in your computer with a .m extension (MATLAB code) by clicking on Open…, or selecting a file from the RECENT FILES list

The EDITOR window

Once you have invoked the editor using any of the ways mentioned previously, a new window will pop up. In this window, you can write, alter, and save your code using a powerful code editor. We will not go into detail here, since to fully comprehend the functionalities of this tool, we first have to learn how to write code in MATLAB.
