MATLAB: Problem having reading the IP address in sorting

countinginputtingip addresssorting

i asked a question here and sir andrei bobrov came out with a good solution here http://www.mathworks.in/matlabcentral/answers/34805-sorting-and-counting
a = [ 1 2 5 7] ; b = [ 9 9 3 4] ;
[aa bb] = ndgrid(a,b);
k = [aa(:) bb(:)];
[n1, n2, n2] = unique(k,'rows');
n3 = histc(n2,1:max(n2));
out = [n1, n3]
but what i ask is if i have to input a cell with values as
['172.20.1.1' '172.20.0.31' '172.20.114.29']
and perform the same program i am getting error as
??? Undefined function or method 'full' for input arguments of type 'cell'.
Error in ==> ndgrid at 38
  varargin{i} = full(varargin{i}); % Make sure everything is full
Error in ==> bob at 3
[aa bb] = ndgrid(a,b);
any solutions please ??

a = { '172.20.113.214'
'85.17.72.66'
'172.20.113.214'
'38.124.168.125'
'46.45.178.252'
'172.20.113.214'
'46.45.178.252'
'172.20.113.214'
'172.20.113.1'
'46.45.178.252'
'172.20.113.214'
'46.45.178.252'
'172.20.113.214'
'46.45.178.252'
'172.20.113.214'
'38.124.168.125'
'172.20.113.214'
'38.113.165.77'
'172.20.113.214'
'38.124.168.125'
'172.20.113.214'
'95.211.85.42'
'172.20.113.214'
'38.113.165.77'
'172.20.113.214'}
[b n n] = unique(a);
out0 = accumarray(n,ones(numel(a),1));
out = [b, num2cell(out0)]
EDIT on comment
[A na na] = unique(a);
[B nb nb] = unique(b);
[av bv] = ndgrid(na,nb);
[v,nab,nab] = unique([av(:) bv(:)],'rows');
k = accumarray(nab,ones(numel(nab),1));
out = [A(v(:,1)) B(v(:,2)) num2cell(k)];
