Detailed Description
Helper class for slices of sparse vectors.
This class stores a reference to a sparse vector and operates on a slice of it. This class is used internally by C-XSC, it should normally not be necessary for the user to use it explicitly.

Member Function Documentation
| const interval cxsc::sivector_slice::operator() | ( | const int | i | ) | const [inline] |
Returns a copy of the i-th (according to the currently used indexing) element of the vector slice.
If the i-th element is explicitly stored, a copy of this value is returned. Otherwise, 0.0 will be returned. Unlike with the []-operator, the data structure remains unchanged either way. Thus this operator should always be used for read-only access to the elements of a sparse vector slice.
Definition at line 1915 of file sivector.hpp.
| interval& cxsc::sivector_slice::operator[] | ( | const int | i | ) | [inline] |
Returns a reference to the i-th (according to the currently used indexing) element of the vector slice.
If the i-th element is explicitly stored, a reference to the value is returned. If is not explicitly stored, it will be added to the data structure as a zero element. The returned reference then points to this new element. Hence the []-operator should only be used for write access to the elements of a sparse vector. Use the ()-operator for read access.
Definition at line 1880 of file sivector.hpp.
| interval cxsc::sivector_slice::operator[] | ( | const int | i | ) | const [inline] |
Returns a copy of the i-th (according to the currently used indexing) element of the vector slice.
If the i-th element is explicitly stored, a copy to the value is returned. If is not explicitly stored, zero will be returned. This is the const-version of this operator, added for convenience. It is suggested to use the ()-operator for read access.
