Matlab Creating Graphical User Interfaces


Once your buttons and plots are in place, the Guide Callback Editor lets you set up the MATLAB code that gets executed when a particular button is pressed. Create GUI figure and code files by selecting the Run command in guide. GUIDE simplifies the process of creating GUIs by automatically generating the GUI M-file directly from your layout.

  • Each of the push buttons creates a different type of plot using the data specified by the current selection in the pop-up menu.
  • And /we can add custom code to add functionality for when the user interacts with the GUI.
  • MATLAB’s abilities can be further utilized through easily programmable graphical user interfaces .
  • Visual Basic makes creating a GUI simple and by using the dynamic data exchange we may easily connect to Matlab.
  • The push button callbacks get data from the handles structure and then plot it.

In event-driven programming, the programmer writes functions to carry out a desired behavior if and when a particular event occurs. The last two lines create a current data value and set it to peaks, and then display the surf plot for peaks. The following figure shows how the app looks when it first displays. To run an app created with GUIDE without opening GUIDE, execute its code file by typing its name. SinDrill is a program that tests the users ability to determine basic parameters of a sinusoid.

If you want to design a more sophisticated user interface or want more control over the app’s behavior, you should consider building a standalone app using App Designer. In this case, we’re getting to plot a surf plot, a mesh plot, and a contour plot. We can also change the string property of the Pop-Up menu to represent each of the datasets we want to display. I can duplicate components by right-clicking and hitting duplicate. I’ll create a complete of three buttons, and that we can align and distribute these buttons by using the alignment tool. Let’s evenly spaced them by 20 pixelsand have them vertically aligned.We can make small adjustments to the object’s positions by using the arrow keys. When we move the panel, all of its contents will move with it.

To add a group, click on the paneloption and stretch it to the required size. We will make our panel interactive by adding some push buttons to it by clicking on the pushbuttons. I’m adding a panel first as opposed to just adding three buttons because it makes it easier to manipulate the buttons as a group. Take a look at this submission of mine from the MATLAB Central File Exchange.

After launching FEATool in MATLAB the GUI will load. The main GUI window which will open is composed of the main GUI compra venta automoviles axes, top menu and toolbar, left vertical mode and tool button bars, and also command log and message windows.

Create three buttons, positioning them approximately as shown in the following figure. This example shows how to use GUIDE to create an app that has a simple user interface , such as the one shown here. Interactive controls are good for creating an easy interface to a live script.

GUIDE generates callbacks for each component in the GUI that requires a callback. Initially, GUIDE generates just a function definition line for each callback. You can add code to the callback to make it perform the operation you want. Matlab is a powerful mathematical tool for matrix calculations and almost any other mathematical function you need. Matlab also has the ability to form windows like applications with its programming language. Select the push button tool from the component palette at the left side of the Layout Editor and drag it into the layout area.

Graphical User Interface, Part 1

It gives a full example of how to read and write data from an OPC server, and how to create and compile a GUI interface with this functionality as well. Always set the tag property of GUI objects to a descriptive and appropriate name.

The functions of these GUI components are explained below. MATLAB’s support for rapid coding into the realm of building GUIs. Guide is a set of MATLAB tools designed to make building GUIs easier and faster. Just as writing math in MATLAB is much like writing it on paper, building a GUI with Guide is much like drawing one on paper. As a result, you can lay out a complex graphical tool in minutes.

This name will be used as the callback function name, so it must conform to the rules for creating variable names . callback functions – functions triggered by events that carry out user-requested behaviorEach component of a GUI has one associated callback functions.
