% Create a table with 5 rows and 4 variables. 
LastName = {'Smith';'Johnson';'Williams';'Jones';'Brown'};
Age = [38;43;38;40;49];
Height = [71;69;64;67;64];

BloodPressure = [124 93; 109 77; 125 83; 117 75; 122 80];

A = table(Age,Height,Weight,BloodPressure,'RowNames',LastName)  

%% 
% Find the size of the table.  Although the |BloodPressure| variable
% contains two columns, |size| only counts the number of variables.
