* 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			`#ifndef EIGEN_LU_MODULE_H`
			`#define EIGEN_LU_MODULE_H`
* 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

big huge changes, so i dont remember everything. * renaming, e.g. LU ---> FullPivLU * split tests framework: more robust, e.g. dont generate empty tests if a number is skipped * make all remaining tests use that splitting, as needed. * Fix 4x4 inversion (see stable branch) * Transform::inverse() and geo_transform test : adapt to new inverse() API, it was also trying to instantiate inverse() for 3x4 matrices. * CMakeLists: more robust regexp to parse the version number * misc fixes in unit tests 2009-10-28 18:19:29 -04:00			`#include "src/LU/FullPivLU.h"`
