  \todo SSome operators could be optimised. To do that, we need to write tests
  and use Valgrind to profile code, shaking cache misses. For example, some
  operators should have iteration first over columns, then rows. ome operators.
  Since those operators are used in many problems, an implementation must be
  efficient.
