MATLAB GUI Tutorial for Beginners

This document provides a tutorial on creating a graphical user interface (GUI) in MATLAB. It discusses initializing the GUIDE tool, creating the visual aspects of the GUI by adding static text, edit text, and pushbutton components and configuring their properties, writing callback code for the components, and launching the GUI. The tutorial walks through building a simple adder GUI as an example, adding two numbers together when the "Add!" button is pressed and displaying the result in a static text component. The GUI allows non-programmers to perform calculations through a user-friendly interface.

MATLAB GUI (Graphical User Interface)

Tutorial for Beginners

By Prof. S. K. Dwivedy
IIT Guwahati
Preprocessing Data:
Why use a GUI in MATLAB?
It makes things simple for the end-users of the program.
Suitable for solving optimization problems.
Initializing GUIDE(GUI Creator)
1. Open up MATLAB. Go to the command window and type in guide.

2. Choose the first option Blank GUI (Default)


Initializing GUIDE (GUI Creator)

3. You should now see either of the following screen:


Initializing GUIDE (GUI
Creator)

4. Before adding components blindly, it is good to have a rough idea


about how you want the graphical part of the GUI to look like:-
Creating the Visual Aspect of the GUI: Part 1
1. For the adder GUI, we will need the following components

Four Static text component

Two Edit text component

One Pushbutton component

2. Edit the properties of these components.
Double click one of the Static Text components. You should see the
property Inspector.

3. Do the same for the next Static Text component, but instead of changing
the String parameter to +, change it to =, and another it to MyAdderGUI.
4. For Static Text component 0, modify the Tag parameter to
answer_staticText.

5. You will have a panel that


look like the following-
Creating the Visual Aspect of the GUI: Part 2
1. Modify the Edit Text components.
Double click on the first Edit Text component, Set the String parameter to 0
Change the Tag parameter to input1_editText

2. The second Edit Text component, set the String parameter to 0


Set the Tag parameter input2_editText.

3. Modify the pushbutton component.


Change the String parameter to Add!
Change the Tag parameter to add_pushbutton.

4. You should have something 5. Rearrange the components as follows:
like this:

5. Save your GUI under any file name. I choose to name mine as
myAdder. When you save this file, MATLAB automatically generates two
files:
myAdder.fig and myAdder.m
The .fig file contains the graphics of your interface.
The .m file contains all the code for the GUI.
Writing the Code for the GUI Callbacks
1. Open up the .m file that was automatically generated when you saved
your GUI.
2. In the MATLAB editor, click on the icon, which will bring up a
list of the functions within the .m file. Select
input1_editText_Callback
Writing the Code for the GUI Callbacks
3. The cursor should take you to the following code block:

4. Add the following code to the bottom of that code block:

5. Add the same block of code to input2_editText_Callback.


Writing the Code for the GUI Callbacks

6. Now we need to edit the add_pushbutton_Callback.

Here is the code that we will add to this callback


Launching the GUI
7. There are two ways to launch your GUI.
The first way: Press the icon on the GUIDE editor

The second method : Launch the GUI from the MATLAB command
prompt.
Type in the name of the GUI at the command prompt.
Launching the GUI

8. The GUI should start running immediately:
