| a default implementation of sparseIterator(), which is implemented |
| by walking over the entries, skipping those that are zero. |
| |
| Concrete subclasses which are SparseVector implementations should |
| make their own sparse iterator, rather than using this one. |
| |
| This implementation might be useful for ArrayRealVector, when expensive |
| operations which preserve the default value are to be done on the entries, |
| and the fraction of non-default values is small (i.e. someone took a |
| SparseVector, and passed it into the copy-constructor of ArrayRealVector)</div> |
