ParCSRAAt for nonsquare matrices

[jesusbonilla]

I am trying to use ParCSRAAt with a rectangular matrix. Is there a reason for the following check or does it simply come from the standard matmul? Everything seems to be working on my end if I just remove it. Thanks!

if (n_cols_A != n_rows_A)

Good question. I think it is fine to remove the check.
