Modifier and Type	Class	Description
class	DenseBlock	This DenseBlock is an abstraction for different dense, row-major matrix formats.
class	DenseBlockBool
class	DenseBlockDRB
class	DenseBlockFP32
class	DenseBlockFP64
class	DenseBlockFP64DEDUP
class	DenseBlockInt32
class	DenseBlockInt64
class	DenseBlockLBool
class	DenseBlockLDRB	Dense Large Row Blocks have multiple 1D arrays (blocks), which contain complete rows.
class	DenseBlockLFP32
class	DenseBlockLFP64
class	DenseBlockLFP64DEDUP
class	DenseBlockLInt32
class	DenseBlockLInt64
class	DenseBlockLString
class	DenseBlockString
class	SparseBlock	This SparseBlock is an abstraction for different sparse matrix formats.
class	SparseBlockCOO	SparseBlock implementation that realizes a traditional 'coordinate matrix' representation, where the entire sparse block is stored as triples in three arrays: row indexes, column indexes, and values, where row indexes and colunm indexes are sorted in order to allow binary search.
class	SparseBlockCSC	SparseBlock implementation that realizes a traditional 'compressed sparse column' representation, where the entire sparse block is stored as three arrays: ptr of length clen+1 to store offsets per column, and indexes/values of length nnz to store row indexes and values of non-zero entries.
class	SparseBlockCSR	SparseBlock implementation that realizes a traditional 'compressed sparse row' representation, where the entire sparse block is stored as three arrays: ptr of length rlen+1 to store offsets per row, and indexes/values of length nnz to store column indexes and values of non-zero entries.
class	SparseBlockDCSR
class	SparseBlockMCSC	SparseBlock implementation that realizes a 'modified compressed sparse column' representation, where each compressed column is stored as a separate SparseRow object which provides flexibility for unsorted column appends without the need for global reshifting of values/indexes but it incurs additional memory overhead per column for object/array headers per column which also slows down memory-bound operations due to higher memory bandwidth requirements.
class	SparseBlockMCSR	SparseBlock implementation that realizes a 'modified compressed sparse row' representation, where each compressed row is stored as a separate SparseRow object which provides flexibility for unsorted row appends without the need for global reshifting of values/indexes but it incurs additional memory overhead per row for object/array headers per row which also slows down memory-bound operations due to higher memory bandwidth requirements.
