I understand that the task is to identify the unique characters in a message and calculate their cardinality or count. We can use the 'unique' function to achieve this:

% Define the message
message = 'your message here';

% Convert the message to lowercase to ensure uniformity
message = lower(message);

% Extract unique characters from the message
unique_chars = unique(message);

% Filter out non-alphabetic characters
alphabet = unique_chars(isstrprop(unique_chars, 'alpha'));

% Calculate the cardinality of the alphabet
cardinality = length(alphabet);

% Display the results
fprintf('The alphabet X is: %s\n', alphabet);
fprintf('The cardinality of the alphabet is: %d\n', cardinality);

Please refer to the following documentation for more information on the 'unique' function: https://www.mathworks.com/help/matlab/ref/double.unique.html
