function to call the gui in matlab

To create a GUI in MATLAB, you can use the GUIDE (Graphical User Interface Development Environment) tool. Once you create a GUI using GUIDE, it will generate a file with a .fig extension and a .m extension. The .fig file contains the layout and design of the GUI, while the .m file contains the code to execute the functionality of the GUI.

To call the GUI from a function in MATLAB, you can use the function guide followed by the name of the .fig file. This will open the GUI and create a set of handles that can be used to interact with the GUI elements.

Here is an example code snippet to call a GUI named myGUI.fig:

main.m
function openGUI()
    guiFig = guide('myGUI.fig'); % open the gui and get its handles
    handles = guihandles(guiFig); % get the handles of the gui elements
    
    % execute code to interact with the gui elements
    % ...
end

Note that it is important to use the handles structure to interact with the GUI elements, as this ensures that the correct instance of the GUI is being accessed.
