Detailed Description

template<typename T>
struct popsparse::CSCMatrix< T >

Sparse matrix stored in compressed sparse columns (CSC) format for a matrix of size [M x N].

There is no explicit encoding of M in the storage. The number of column indices is equal to (N/number of columns in block) + 1. The case of element sparsity is treated as a special case with block size equal to {number of rows in block, number of columns in block} = {1, 1}.

Member Data Documentation

columnIndices

template<typename T >

std::vector<std::size_t> popsparse::CSCMatrix< T >::columnIndices

Indices where non-zero values for each column block starts.

There are a total of N/block size + 1 entries with the last entry equal to nzValues.

nzValues

template<typename T >

std::vector<T> popsparse::CSCMatrix< T >::nzValues

The non-zero values of the sparse matrix.

The number of values is always an integer multiple of the block size.

rowIndices

template<typename T >

std::vector<std::size_t> popsparse::CSCMatrix< T >::rowIndices

The row index of each block in nzValues.

There are as many entries as the number of blocks in nzValues.
