Has someone ever seen in literature indicating the row of a matrix with the index on the left side?

I mean, the column i of a matrix A is indicated with $\displaystyle a_i$

With this (universal) notation the row j of A can be indicated as $\displaystyle ((A^T)_j)^T$

That's cumbersome.

So the question: has anyone ever seen in literature indicating the row j of A as $\displaystyle _{_j}a$

If yes, pls tell me where, which text. Thank you.
