I have a map with some keys which has multiple number of values in it How can I access those values for each key.
these show the size of the array of the value but not the values itself.
for u = keys(mp)
mu = values(mp,u);
disp(mu)
for v = mu
disp(v);
end
disp('-----------ended------------------')
end

mp = dictionary(["a1", "a2", "a3"], {1, [2 3], "str"})
k = keys(mp);
v = values(mp)
for i = 1:length(v)
disp(v(i));
end

Check the below code may be help you.
% Create and populate the map
mp = containers.Map;
mp('key1') = [1, 2, 3];
mp('key2') = {'value1', 'value2', 'value3'};
mp('key3') = [10, 20, 30, 40];
% Iterate over each key in the map
for u = keys(mp)
key = u{1}; % Extract the key from the cell array
% Access the values associated with the current key
valuesArray = mp(key);
% Iterate over each value in the values array
for i = 1:numel(valuesArray)
value = valuesArray(i);
disp(value);
end
disp('-----------ended------------------')
end
