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 CXSC, it should normally not be necessary for the user to use it explicitly.
Definition at line 4063 of file scivector.hpp.
const cinterval cxsc::scivector_slice::operator()  (  const int  i  )  const [inline] 
Returns a copy of the ith (according to the currently used indexing) element of the vector slice.
If the ith 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 readonly access to the elements of a sparse vector slice.
Definition at line 4147 of file scivector.hpp.
cinterval& cxsc::scivector_slice::operator[]  (  const int  i  )  [inline] 
Returns a reference to the ith (according to the currently used indexing) element of the vector slice.
If the ith 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 4112 of file scivector.hpp.
cinterval cxsc::scivector_slice::operator[]  (  const int  i  )  const [inline] 
Returns a copy of the ith (according to the currently used indexing) element of the vector slice.
If the ith element is explicitly stored, a copy to the value is returned. If is not explicitly stored, zero will be returned. This is the constversion of this operator, added for convenience. It is suggested to use the ()operator for read access.
