Interaction Between Separate Callbacks - Updating The "handles" Structure13:42
Refactor MATLAB guide code by validating fields in callbacks and using the handles structure to pass data between callbacks. Update handles with new values and force callbacks when needed.
The "guidata" Function Explained Again3:10
Explore the guidata function in Matlab guide, tracing how a toggle left callback updates the handles structure and keeps data synchronized through the data function.
Second Project Source Code0:03

What is a Toolbar and Adding a Predefined Toolbar Menu Items4:21

Creating Your Own Custom Toolbars5:37
Create a custom toolbar in MATLAB guide by selecting a type, push or toggle; name the tag; customize or import an icon; and define a callback that clears the axes.

Creating a Menubar type Menu - Save and Load Data for Your Application11:20
Build a MATLAB GUI with a menu bar and context menus, customize items and callbacks, and implement save and load to preserve power coefficients.
Creating a Context type Menu - Change the Axes Properties10:03
Learn to create and attach context menus in MATLAB GUIDE, define callbacks, and change axis line colors (green, red, blue) through nested menu items tied to specific plot elements.
Copying an Axes into the Windows Clipboard From Your Application3:21
Add a context menu item to copy a MATLAB axes to the Windows clipboard, using an invisible figure to transfer the plot for pasting into Word.
First Project Source Code with Menus0:03

Packaging the Application into a MATLAB Application6:59

Why to Develop Graphical User Interface?

Often times people judge a book by the cover. And for sure the code that you wrote works flawlessly, but does it have a good looking cover and how easy is it to use it? And if you want your code to be used by people who have no coding skills or at the very least, their skills are not good enough to understand it. Why not wrap your code with an interface that will enable anyone to use it? Let us help you with this!

The Development of a intuitive graphical user interface can make your work more popular, since it will be available to a much broader audience of people, that way it can reach more people, and be valued by more people. The graphical user interface, gives the ability to the end user to use the “point and click” strategy, to work more easily with the software application, so the need for the user to know the actual language in which it was written is eliminated.

Why with MATLAB?

Matlab (Matrix Laboratory) is a programming language of a higher level with interactive development environment, that can satisfy the needs even of the most demanding software developers.

The advantages of MATLAB are:

Specially designed to work with data structures
Built on a modular principle from many different toolboxes, that make specialized functions available for many scientific fields – finances, cartography, numerical biology, data processing, signal processing, parallel calculations and many others)
Platform independent language – it works on any Operating System
It can directly communicate and operate with hardware periphery (sound cards, video cameras, Arduino, DAQ systems and many more)
Gives you the ability to package your code into an (.exe) executable file
Rich documentation with thorough explanations of all of its functions, available both offline in the MATLAB environment itself, and in the MATLAB Central website

Why with MATLAB GUIDE?

GUIDE (Graphical User Interface Development Environment) is a MATLAB integrated working environment that provides instruments and techniques for accelerated, easy and intuitive design and development of GUI for user oriented applications. The approach is straightforward, arrange the user interface elements using the GUIDE Layout Editor, then GUIDE will automatically generate the code behind these elements (Callbacks), which are responsible for the behavior of each of your elements, and finally populate these automatically generated Callbacks with their appropriate behaviors (code), package the app and make it available to the end users.

In conclusion:

If you ever wanted to be a movie producer, this is a great opportunity – become the screenwriter of your own graphical user interface and a producer of its implementation. Create the product, share it with the users, and enjoy the end result! Don’t be the only one who understands and uses your own code, wrap it in an interface and make it available to the broader audience! As always – Express Yourself!
