We discussed this already and decided not to provide such a function.
The reasons are:
1. clear() may be misleading, because it could mean "set all values to
zero" (linear algebra view) or "set size to zero" (STL view)
2. there is already a good (=readable) way to zero a matrix: assign the
zero_matrix.
3. Its easy to create a free function set_to_zero() that fills a matrix
with zeros.
