I am preparing some data for the classifier app in MATLAB and want to label my data i.e. I want to add a single column containing 8006 zeroes followed by 3400 ones, 2300 twos, 627 threes, 672 fours and 1006 fives. I have a .mat file for my data.

You can make a column vector like this
numRows = [8006,3400,2300,627,672,1006]
col = [];
for k = 1 : length(numRows)
col = [col; (k-1)*ones(numRows(k), 1)];
end
