Please let me know if I understood correctly your question.

Month={'January'; 'January'; 'February'; 'February'};
set_of_month=unique(Month);
% Add a matrix of zeros to host the dummy variables
dum=zeros(length(Month),length(set_of_month));
T=[table(Month) array2table(dum)];
% Add the labels
T.Properties.VariableNames(2:end)=set_of_month;
% Add the ones in the corresponding position
 for i=1:length(set_of_month)
    for j=1:height(T)
        if strcmp(T.Month{j},set_of_month{i})
            T{j,i+1}=1;
        end
    end
 end
 
 disp(T)
%       Month        February    January
%     ____________    ________    _______

%     {'January' }       0           1   

%     {'January' }       0           1   
%     {'February'}       1           0   

%     {'February'}       1           0
