|
The raw iterator is a method for accessing all nonzero entries in the matrix in some unspecified order.
This can be used, e.g. to reduce all matrix entries modulo a prime before passing the matrix into an algorithm.
|
Iterator | Begin () |
| Begin.
|
|
Iterator | End () |
| End.
|
|
ConstIterator | Begin () const |
| const Begin.
|
|
ConstIterator | End () const |
| const End
|
|
|
The index iterator gives the row, column indices of all matrix elements in the same order as the raw iterator above.
Its value type is an STL pair with the row and column indices, starting at 0, in the first and second positions, respectively.
