Details:

Both "image" and "imagesc" functions implement the "Parent" property. However
it is currently missing from the "imshow" function. It shows a warning and
ignores the argument...

Note that IMSHOW uses IMAGE/IMAGESC underneath, so I expect it wouldn't be
difficult to add support for it.

This property is especially useful when showing images in different subplots
inside a loop. Here is an example:


h(1) = subplot(121);
h(2) = subplot(122);
for i=1:2
    imshow(rand(10), 'Parent',h(i))
end


The workaround is to manually set the current axis before calling IMSHOW:


for i=1:2
    axes(h(i))
    imshow(rand(10))
end
