Maybe I missed the point here but after R.<x1,x2>=QQ[] M=matrix(R,1,2,[x1+x2,x1*x2])
you can get at the entries like this: sage: M[0,0] x1 + x2 sage: M[0,1] x1*x2 where the only non-obvious thing to a mathematician is that the row/col indices start at at 0. The list() discussion seems separate to me.
