Gael Guennebaud	64169389ed	added an *optional* Eigen2 dynamic library. ... it allows the possiblity to save some compilation time by linking to it *and* defining the token EIGEN_EXTERN_INSTANCIATIONS	2008-05-31 23:21:49 +00:00
Gael Guennebaud	8711e26c8a	* change Flagged to take into account NestByValue only ... * bugfix in Assign and cache friendly product (weird that worked before) * improved argument evaluation in Product	2008-05-28 22:11:47 +00:00
Gael Guennebaud	45cda6704a	* Draft of a eigenvalues solver ... (does not support complex and does not re-use the QR decomposition) * Rewrite the cache friendly product to have only one instance per scalar type ! This significantly speeds up compilation time and reduces executable size. The current drawback is that some trivial expressions might be evaluated like conjugate or negate. * Renamed "cache optimal" to "cache friendly" * Added the ability to directly access matrix data of some expressions via: - the stride()/_stride() methods - DirectAccessBit flag (replace ReferencableBit)	2008-05-12 10:23:09 +00:00
