Hi everybody,
I want to create a 'Start'- button that opens the connected webcam and displays the video in an UI-Axes. If i clicked 'start', the button should change to 'stop' so that I can press it again to stop the camera. So far I've got 2 different buttons programmed.
Can anyone help me to connect these two buttons?
Thanks a lot for your help!
Best regards.

For fun, one-liner
uibutton('Text','Start','ButtonPushedFcn','set(gcbo,''text'',setdiff(["Start","Stop"],get(gcbo,''text'')))')
The general approach is, in your callback function of the button, get and set the text of the button.
