| class | SSVector |
| | Semi sparse vector.This class implements Semi Sparse Vectors. Such are DVectors where the indices of its nonzero elements can be stored in an extra IdxSet. Only elements with absolute value > epsilon are considered to be nonzero. Since really storing the nonzeros is not always convenient, an SSVector provides two different stati: setup and not setup. An SSVector being setup means that the nonzero indices are available, otherwise an SSVector is just an ordinary Vector with an empty IdxSet. Note that due to arithmetic operation, zeros can slip in, i.e., it is only guaranteed that at least every non-zero is in the IdxSet. More...
