MATLAB: How to select particular elements from an array

cell arrays

Hi, I have an array A = [1 2 3 4 5 6 7 8 9 10], and an another array of lower size B = [2 6 9]..I need to logically find components from B in A so that the result C comes as [1 0 1 1 1 0 1 1 0 1] or [0 1 0 0 0 1 0 0 1 0]..

thanks, Amitrajit

>> A = [1;6;9;4;2;8];
>> M = tril(repmat(A.',6,1))
M =  
   1   0   0   0   0   0
   1   6   0   0   0   0
   1   6   9   0   0   0
   1   6   9   4   0   0
   1   6   9   4   2   0
   1   6   9   4   2   8

MATLAB: Using ismember to seek out pairs

   A = [1 2 5; 4 5 7; 7 8 9; 4 7 10; 6 7 2]
B = [2 3; 4 9; 7 9; 7 6]
for k=1:size(A,1)
    out(k)=any(all(ismember(B,A(k,:)),2));
end
out

%or

 out=arrayfun(@(x) any(all(ismember(B,A(x,:)),2)),1:size(A,1))
