map Size in MATLAB

In MATLAB, you can get the size of the hash using the size function.

Here's an example of how to get the size of a hash created using the containers.Map function:

% Create a hash with some key-value pairs
myMap = containers.Map;
myMap('key1') = 10;
myMap('key2') = 20;
myMap('key3') = 30;
% Get the size of the hash

sizeMyMap = size(myMap);

disp(sizeMyMap);

Output:

1     1

In the above example, the size function returns a 1x1 matrix, which means that the hash has only one element.

Alternatively, you can also use the length function to get the number of elements in a hash:

% Get the length of the hash
lengthMyMap = length(myMap);
disp(lengthMyMap);

Output:

3

In this case, the length function returns the number of key-value pairs in the hash, which is 3.
