Gael Guennebaud	c4c70669d1	Big rewrite in the Sparse module: SparseMatrixBase no longer inherits MatrixBase. ... That means a lot of features which were available for sparse matrices via the dense (and super slow) implemention are no longer available. All features which make sense for sparse matrices (aka can be implemented efficiently) will be implemented soon, but don't expect to see an API as rich as for the dense path. Other changes: * no block(), row(), col() anymore. * instead use .innerVector() to get a col or row vector of a matrix. * .segment(), start(), end() will be back soon, not sure for block() * faster cwise product	2009-01-14 14:24:10 +00:00
Gael Guennebaud	709e903335	Sparse module: ... * extend unit tests * add support for generic sum reduction and dot product * optimize the cwise()* : this is a special case of CwiseBinaryOp where we only have to process the coeffs which are not null for *both* matrices. Perhaps there exist some other binary operations like that ?	2009-01-07 17:01:57 +00:00
