Comment (by Bouillaguet):
Examples of things that are presently bad (where a sparse matrix is
converted to a dense representation) :
* kernel, determinant of sparse integers matrices
* rank of integers matrices relies on echelonization, which very likely
switch it to dense. Linbox has other ways of dealing with this.
* elementary divisors and smith form of sparse integer matrices (idem).
