Or automatic, e.g., src/ksp/ksp/examples/tutorials/ex2.c (or any other
example that solves something)

./ex2 -ksp_view_mat binary:my-file-name -ksp_view_rhs binary:my-file-name::append

Then load it up:
$ octave -q
octave:1> [A,b] = PetscBinaryRead('foo');
octave:2> [size(A); size(b)]                                                                                                                                                 
ans =
