What are the row and column subscripts needed to access the 167th element of the fourth cell

the value shows up in vectors.

All depends on what the array dimensions are; you don't need them anyway if you wish the Nth element, just use one-dimensional subscripting and Matlab will just do the right thing.

If you do want the subscripts for some other purpose, see

doc sub2ind
doc ind2sub

for the case to translate to/from one representation to the other.
