MATLAB: Manipolation of Cell Arrays.

cellcell arraycell arrays

I have {A}=<250×22>cell. thanks to another question I'm able to know the pairs of two colums of {A} for example I have just these three combination :{a}&{b} or {b}&{z} or {r}&{t}. What I would like to create three different cell arrays based on the three combination.

A={'a','b',1 2 3;
    'a','b',3 4 5;
    'b','z',3 4 5;
    'b','z',4 5 6;
    'r','t',5 6 7;
    'r','t',6 7 8};
UniqComb={'a','b';'b','z';'r','t'};
N=size(UniqComb,1);
Groups=cell(N,1);
for k=1:N
    index=and(strcmp(A(:,1),UniqComb(k,1)),strcmp(A(:,2),UniqComb(k,2)));
    Groups{k}=A(index,:);
end
    >> Groups{1}
    Groups{2}
    Groups{3}
  ans = 
      'a'    'b'    [1]    [2]    [3]
      'a'    'b'    [3]    [4]    [5]
  ans = 
      'b'    'z'    [3]    [4]    [5]
      'b'    'z'    [4]    [5]    [6]
  ans = 
      'r'    't'    [5]    [6]    [7]
      'r'    't'    [6]    [7]    [8]
