Summation of Container Values

How can I sum the Container values?

example:

I have Container A and B

A = containers.Map({'W', 'C'},[1,2]);

B = containers.Map({'W', 'Co'},[3,4]);

And I want sum A and B

So the result should be:

W: 4

C: 2

Co: 4

How can I do that?

The code below provides a generalized approach to merge maps and if there is a collision because of same key add those values.

allKeys0   = cellfun(@keys, maps, 'UniformOutput', false);
[allKeys, ~, m] = unique([allKeys0{:}]);
allValues0 = cellfun(@values, maps, 'UniformOutput', false);
allValues = cell2mat([allValues0{:}]);
sumValues = arrayfun(@(x) sum(allValues(m==x)), 1:numel(allKeys));
mergedMap = containers.Map(allKeys, sumValues);
