How to iterate and access over map key values

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"})

mp = 
  dictionary (string ⟼ cell) with 3 entries:

    "a1" ⟼ {[1]}
    "a2" ⟼ {[2 3]}
    "a3" ⟼ {["str"]}

k = keys(mp);
v = values(mp)

v = 3×1 cell array
    {[    1]}
    {[  2 3]}
    {["str"]}

for i = 1:length(v)
    disp(v(i));
end

    {[1]}

    {[2 3]}

    {["str"]}

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
