Detailed Description

Extremely simple data container that represents a sparse row-oriented matrix-graph. Purely serial. If it is used to store the local portion of a distributed matrix-graph, the calling code is responsible for all knowledge related to parallelism.

rowNumbers

std::vector<int> fei::SparseRowGraph::rowNumbers

Local row-numbers.

rowOffsets

std::vector<int> fei::SparseRowGraph::rowOffsets

The starting offset of each row in the packedColumnIndices vector. The i-th row corresponds to positions rowOffsets[i] through rowOffsets[i+1]-1. Note that rowOffsets should have length rowNumbers.size()+1, and rowOffsets[rowNumbers.size()] == packedColumnIndices.size().

packedColumnIndices

std::vector<int> fei::SparseRowGraph::packedColumnIndices

Contiguous array of column-indices for all local rows. See the comments for the 'rowOffsets' attribute, for information about accessing column-indices for a particular row, etc.
