Benoit Jacob	6f09d3a67d	- many updates after Cwise change ... - fix compilation in product.cpp with std::complex - fix bug in MatrixBase::operator!=	2008-07-08 07:56:01 +00:00
Gael Guennebaud	4af7089ab8	* Added a generalized eigen solver for the selfadjoint case. ... (as new members to SelfAdjointEigenSolver) The QR module now depends on Cholesky. * Fix Transpose to correctly preserve the *TriangularBit.	2008-06-14 19:42:12 +00:00
Gael Guennebaud	001b01a290	Rewrite from scratch of the eigen solver for symmetric matrices ... which now supports selfadjoint matrix. The implementation follows Golub's famous book.	2008-06-02 00:30:26 +00:00
Gael Guennebaud	a2f71f9d7e	updated EigenSolver to use .coeff / .coeffRef	2008-05-31 16:31:10 +00:00
Gael Guennebaud	559233c73e	* fix the QR module to use extract/part instead of the previous triangular stuff ... * added qr and eigensolver tests * fix a compilation warning in Matrix copy constructor	2008-05-27 09:16:27 +00:00
Gael Guennebaud	fd2e9e5c3c	* Clean a bit the eigenvalue solver: if the matrix is known to be ... selfadjoint at compile time, then it returns real eigenvalues. * Fix a couple of bugs with the new product.	2008-05-13 07:40:25 +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
