I need to get a numeric handle to a patch object in R2017A. Both get(gca,'Children') and findobj return a struct with all the graphic object properties except the handle. A post referring to R2014 mentions I can get this using the 'Number' property, but this doesn't seem to exist anymore. Here is the link to the article: https://www.mathworks.com/help/matlab/graphics_transition/graphics-handles-are-now-objects-not-doubles.html#budq3uo-1
This seems like it should be simple but I am stuck!
