Advanced MATLAB: ButtonDownFcn 1

Posted by Doug Hull,

This is the next in a series of advanced topics in MATLAB. My definition of “Advanced” is somewhat nebulous and arbitrary, so even newer users can give this a watch. Two and a half minute video shows how to use buttondownfcn to get the current point. This can be a fundamental skill that underlies many advanced GUIs.

Thanks for another great tutorial.

If my plot were actually a 2-D figure, would it be possible to get the (x,y) and also the intensity at that spot (x/255)?

Thanks,
Daphne
