Add a matrix of strings

% Add a matrix of zeros to host the dummy variables
dum=zeros(length(Month),length(set_of_month));
T=[table(Month) array2table(dum)];

will add a matrix of zeros. But I want to add a matrix of some strings like

--------------
United States
United States

Then how can one modify the above code?

**********

This is what I did:

dum=zeros(height(T),1)
dum1=num2cell(dum)
dum1(dum==0)={'US'}
T1=cell2table(dum1) 
T=[T T1]

[Walter Roberson]

T = table(Month);
T.Country(:) = "United States";

or consider

T = table(Month);
T.Country(:) = categorical("United States");

[Walter Roberson]

Month = randi(12, 7, 1);
T = table(Month);
T.Country(:) = "United States";
T

T = 7x2 table
    Month        Country    
    _____    _______________

      1      "United States"
      2      "United States"
      5      "United States"
      3      "United States"
      3      "United States"
      4      "United States"
      4      "United States"

T2 = table(Month);
T2.Country(:) = categorical("United States");
T2

T2 = 7x2 table
    Month       Country   
    _____    _____________

      1      United States
      2      United States
      5      United States
      3      United States
      3      United States
      4      United States
      4      United States

No problem -- not unless you already happened to have a table variable named Country; or unless you neglected to remove the table variables that resulted from your earlier experiments.
