I have three matrices(see below), I would like to have excel lookup based on
the column and row(ex. [3,7]) and search the other matrices for the same
column and row numbers and add them together(ex. [3,7] + [3,7] = Y+ J).
However I am not sure how to go about doing this. Any help would be greatly
appreciated.


[1 2 5 6]
A B D E [1]
B E H F [2]
J U T D [5]
U Y P P [6]

[2 3 6 7]
A B D E [2]
B E G F [3]
J S D D [6]
U Y P P [7]

[3 4 7 8]
A B D E [3]
B E G F [4]
J S D D [7]
U Y P P [8]
