Matlab: How to obtain all the axes handles in a figure handle?

Question

How do I obtain all the axes handles in a figure handle?

Given the figure handle hf, I found that get(hf, \'children\') may return the hand

Jonas' solution didn't work for me, because there were some handles referring to legends. Surprisingly, legends seem to be implemented as axes, at least in Matlab 2010a. Here is a solution if you only want the axes, not any legends or other stuff.

axesHandles = get(fig, 'Children');
classHandles = handle(axesHandles);
count = length(axesHandles);
isNotInstanceOfSubtype = false(1, count);
for i = 1:count
    isNotInstanceOfSubtype(i) = strcmp(class(classHandles(i)), 'axes') == 1;
end
axesHandles = axesHandles(isNotInstanceOfSubtype);

The script works by sorting out handles which reveal to be of a sub-type of type axes, for example scribe.legend.

A warning for those trying to improve the above code snippet: using something like

classHandles = cellfun(@(x) handle(x), axesHandles)

might not work as intended:

??? Error using ==> cellfun
scribe.legend type is not currently implemented.
