If 3x3 matrix (i.e. without transformations) is used then matrix is
same, regardless of multiplying vector row with matrix (i.e. vectors are
seen as rows) or matrix with vector column (vectors are seen as
columns). Difference comes, when You use 4x4 matrix, then matrix is
different (translation is either in last row or column).
