How it is possible to count occurrence of keys and values of Containers.Map A in B?
A = containers.Map({1026,1033,1038,1042},...
{[605.914,48.521],[490.6086 23.7932],[257.558,67.625],[439.090,225.924]});
B = containers.Map({1025,1026,1028,1029,1031,1033,1035,1037,1038},...
{[397.494,168.066],[605.914,48.521],[295.712,176.770],[226.249,209.288],...
[52.573,278.126],[490.6086 23.7932],[50.747,213.198],[38.992,4.417],[257.558,67.625]});
Thank you!!

Just considering the keys, you can use ismember (though I'm not sure why there's a limitation that cells must be cell arrays of character vectors, and can't be numbers..)
[mask] = ismember(cell2mat(B.keys),cell2mat(A.keys))
cnt = sum(mask)
[mask] = ismember(B.keys,A.keys)
If you need to check if values are the same, you can iterate through the matched keys and use isequal()

Yes, sorry should have clarified the last line doesn't work, but seems like a silly limitation by TMW to me. Glad it helps!
