I want to create a first column for my table, after a loop. I tried like this:
%N(mxn)
i=1;
while i<= size(N,1)
capa(i) = fprintf('Bar #',int2str(i));
i=i+1;
end
Furthermore I used sprintf.
The result in this case of three rows, it would be:
Bar 1
Bar 2
Bar 3

See this example
t = array2table(rand(3)); % example table
rows = compose('Bar %d', [1 2 3]);
rows = vertcat(rows{:});
T = [table(rows, 'VariableNames', {'labels'}) t];
