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
