container map same key more value in matlab

In MATLAB, you can use the containers.Map class to map the same key to multiple values. The basic idea is to create a Map object where the keys are unique and the values are cell arrays.

Here's an example of how to container map the same key to multiple values in MATLAB:

main.m
% Create a Map object
myMap = containers.Map();

% Add values to the map
key = 'mykey';
value1 = 'value1';
value2 = 'value2';
value3 = 'value3';

% Check if the key already exists in the map
if isKey(myMap, key)
    % If the key exists, append the new value to the existing cell array
    myMap(key) = [myMap(key), {value1}];
else
    % If the key doesn't exist, create a new cell array for the value
    myMap(key) = {value1};
end

% Append additional values to the same key
myMap(key) = [myMap(key), {value2, value3}];

% Access the values associated with the key
values = myMap(key);

In this example, the key 'mykey' is associated with three values: 'value1', 'value2', and 'value3'. The values are stored in a cell array within the Map object.

You can access the values associated with a key using the syntax myMap(key). The returned value will be a cell array containing all the values associated with that key.

Note that if you plan to use numeric keys, you can't use the dot notation (myMap.key) and you must use the explicit indexing syntax (myMap('key')).

Hope this helps!
