Benoit Jacob	6747b45ae7	for 4x4 matrices implement the special algorithm that Markos proposed, ... falling back to the general algorithm in the bad case.	2008-04-15 20:15:36 +00:00
Benoit Jacob	2a86f052a5	- optimized determinant calculations for small matrices (size <= 4) ... (only 30 muls for size 4) - rework the matrix inversion: now using cofactor technique for size<=3, so the ugly unrolling is only used for size 4 anymore, and even there I'm looking to get rid of it.	2008-04-14 17:07:12 +00:00
Benoit Jacob	ea3ccb1e8c	* Start of the LU module, with matrix inversion already there and ... fully optimized. * Even if LargeBit is set, only parallelize for large enough objects (controlled by EIGEN_PARALLELIZATION_TRESHOLD).	2008-04-14 08:20:24 +00:00
