Examples
Create a Map object containing the names
of several US states and the capital city of each:
US_Capitals = containers.Map( ...
{'Arizona', 'Nebraska', 'Nevada', 'New York', ...
'Georgia', 'Alaska', 'Vermont', 'Oregon'}, ...
{'Phoenix', 'Lincoln', 'Carson City', 'Albany', ...
'Atlanta', 'Juneau', 'Montpelier', 'Salem'});
After checking how many keys there are in the US_Capitals map,
remove the key-value pair with key name Oregon from
it:
US_Capitals.Count
ans =
8
remove(US_Capitals, 'Oregon');
US_Capitals.Count
ans =
7Remove three more key-value pairs from the map:
remove(US_Capitals, {'Nebraska', 'Nevada', 'New York'});
US_Capitals.Count
ans =
