I understand that you want to access the last row of a matrix but do not know the matrix size. Please use the Submatrix block, set it's block parameters Starting row: last and keep the other parameters at their default settings. This should give you the last row.

Refer to the Submatrix Block document for more information on how to use and set the Submatrix Block Parameters.
