I want to use impoint in the gui that I've created, but I don't know how should I do that. There is a part in my gui that the user should be able to choose 2 pixel on the loaded image and then the program runs another function with the coordinates of those 2 pixels. I want also that the program updates the coordinates when the user changes that points.

adding this in your code might work

See help ginput. A minimal working example:
pcolor(rand);
[x,y] = ginput(1);
% User clicks a value.
x = floor(x);
y = floor(y);

When I'm using impoint() the points are draggable. Is there some way you can post a sample of your code?
