To enable file input in a MATLAB GUI, you can use the uigetfile
function to create a dialog box that allows the user to select a file on their computer. You can create a push button or menu item object in your GUI, and specify a callback function that opens the uigetfile
dialog box.
Here's an example of how to create a push button that opens a file selection dialog box in a MATLAB GUI:
main.m671 chars17 lines
In this example, the uicontrol
function is used to create a push button object with a label "Select File". The Callback
property is set to the name of a callback function, in this case select_file_callback
.
The select_file_callback
function is defined to open the file selection dialog box using uigetfile
. The function checks if the user cancelled the file selection, and displays a message indicating the selected file. You can perform further processing on the selected file within the callback function.
Note that you can customize the file types that are displayed in the dialog box by changing the file filter parameter passed to uigetfile
. In this example, the file types displayed are text files with the extension ".txt", CSV files with the extension ".csv", and MATLAB MAT-files with the extension ".mat".
