I'm trying to create an app in App Designer where I display an image on a UIAxes and then capture the position of the mouse when a user clicks on that image and then display the captured mouse position in an edit field. I have created a ButtonDownFcn associated with the image but when I click on the image I get:
Undefined function 'im_ButtonDownFcn' for input arguments of type 'matlab.graphics.primitive.Image'.
Error while evaluating Image ButtonDownFcn.
My code is attached, any help would be much appreciated.
