Benoit Jacob	7c14e1eac4	add partial-pivoting LU decomposition ... the name 'PartialLU' is not meant to be definitive! make inverse() and determinant() use it, so it's *almost* considered well tested.	2009-05-13 02:02:22 +00:00
Benoit Jacob	8106d35408	Patch by Kenneth Riddile: disable MSVC warnings, reenable them outside ... of Eigen, and add a MSVC-friendly path in StaticAssert.	2008-12-18 20:48:02 +00:00
Benoit Jacob	f04c1cb774	Complete LU documentation	2008-08-11 21:26:37 +00:00
Benoit Jacob	c2f8ecf466	* LU decomposition, supporting all rectangular matrices, with full ... pivoting for better numerical stability. For now the only application is determinant. * New determinant unit-test. * Disable most of Swap.h for now as it makes LU fail (mysterious). Anyway Swap needs a big overhaul as proposed on IRC. * Remnants of old class Inverse removed. * Some warnings fixed.	2008-08-04 04:45:59 +00:00
Gael Guennebaud	172000aaeb	Add .perpendicular() function in Geometry module (adapted from Eigen1) ... Documentation: * add an overview for each module. * add an example for .all() and Cwise::operator<	2008-07-22 10:54:42 +00:00
Benoit Jacob	3eccfd1a78	-fix certain #includes ... -fix CMakeLists, public headers weren't getting installed	2008-05-12 21:15:17 +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
