can anybody help me to execute the following code

    numUsers = diag([1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20]);
    N_UE = 1 : numUsers
    % Get a scrambled array
    s = N_UE(randperm(length(N_UE)))
    numGroups = 5; % Need to divide s up into 5 groups
    divisions = sort(randperm(numUsers-2, numGroups-1) + 1, 'ascend')
    divisions = [0, divisions, numUsers]
    % Create cell array with random number of users in each groups
    groups = cell(1, numGroups);
    for k = 1 : numGroups
      indexes = divisions(k)+1:divisions(k+1);
      % Assign users to the kth group:
      usersInThisGroups = length(indexes);
      fprintf('Assigning %d users (indexes %d to %d) to group %d.\n', ...
        usersInThisGroups, divisions(k)+1,divisions(k+1), k);
      groups{k} = s(indexes);
    end
    celldisp(groups); % Display groups in command window.

@Prabha Kumaresan: please stop spamming the same question repeatedly. It does not get you help faster, but in fact makes it harder for us to help you.
