I *think* that your question is whether a sparse matrix is characterized
only by its entries (which you can write out) or whether there is some
additional hidden state that also affects the solution of a linear
system. The answer is the former. If you output the entries of a matrix
and a right hand side and solve the linear system in a different
environment, then you better get the same result.
