length (Map) - Length of containers.Map object
Syntax
L = length(M)
Description
L = length(M) returns the number of pairs in
the map M. The number returned by this method is
equivalent to size(M,1).

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'});
Find out how many keys are in the map:
length(US_Capitals)
ans =
8
This should be equal to the Count property
for the object:
length(US_Capitals) == US_Capitals.Count
ans =
1
