Ok so - This may be a little hard to explain to forgive me.

I have a selection of array of letters (lets call is matrix X), e.g

A B C; A C D; A D G; A E H; Q N J; A G K; A H I; A I W;

Defined as a 8x3 cell (in this case). I also have another array (matrix Y) (11x2 cell) of similar format (populated with letters).

What I want to do is write some code which looks through each row of matrix X in turn and returns a "1" if the row contains both letters in any row of matrix Y and a "0" if not.

For example, matrix X is as above and matrix Y is,

A F; E D; E C; J I; J H; M L; V T; V U; Q J; Q O; Q P;

In this case, the 5th row of matrix X would agree with the statement as "Q" and "N" are present (as in the 9th row of matrix Y). The other rows in X are all fine and would return "1".

I hope that makes sense - happy to explain further if necc.

Best,

Craig

You mean Q and J in the fifth row of X
