Have a read here and here. It will greatly improve your chances of getting an answer.

Do you expect people to copy your data from a picture? You're asking people for help. You should make it as easy as you can for people to help you.

What determines that (1,15) should be selected from B and (1,9) from C? And how does that mean you need (15,1,9) from D? If you find (1,15) in B and (2,9) in C, should you select (15,1,9) or (15,2,9) from D?

look at the position of the row that is worth 0 in matrix A, the row that is worth 0 in matrix A will determine the next step. If the number 0 in matrix A is in row 2, then in matrix B the values in row 2 are paired with what column, as well as in matrix C row 2 is paired with what column.

Unfortunately for you, that explanation doesn't help me.

I suspect the find function does everything you need. To give you a complete answer I need to understand better how exactly you want to process these arrays.

Did you try to write any code? Did you read the two threads I linked in my initial comment?
