how do i change properties of a selected node in matlab

To change properties of a selected node in MATLAB, you need to first select the node in question. This can be done using the appropriate MATLAB function depending on the type of GUI component you are working with. Once the node has been selected, its properties can be accessed and changed using the 'set' command.

Here is an example code snippet that shows how to change the color of a selected push button in a MATLAB GUI:

main.m
% Select the push button you want to modify
my_button = handles.pushbutton1; % handles.pushbutton1 is the handle of the push button

% Change the background color of the button to red
set(my_button, 'BackgroundColor', 'red');

In this example, we first select the push button with handle 'pushbutton1' and assign it to the variable 'my_button'. We then use the 'set' command to change the 'BackgroundColor' property of the button to 'red'. This will change the color of the button to red for the user.
