I have 2 cells
A = {5;5;[];[];[];[];[];[]};
B = {5;13;4;12;12;12;17;14};
As you see, index one of cell A equals to cell B.
I want to find this index. The below code is not correct for this example.
ismember(cell2mat(A),cell2mat(B),'rows');

Do I understand correctly that for each element of A, you want a list of the indices in B for which any row of the A element matches any row of the B element?
I thought at first you were asking about whether corresponding positions matched, but your A has 9 entries where your B has 8 entries, so you must be wanting to compare every A to every B... by rows??
Could you confirm that in some cases you really will have rows in A or B? And will the entries always be empty or have the same number of columns?

This does not account for the 'rows' shown in the posting, and does not account for A and B being different lengths.

True sir Walter, assumption was it had equal elements with each as vectors.
