*	* extractRotation ---> rotation	Benoit Jacob	2008-12-19
\| \| \| \| \|	* expand the geometry/Transform tests, after Mek's reports * fix my own stupidity in eigensolver test
*	SelfAdjointEigenSolver: add operatorSqrt() and operatorInverseSqrt()	Benoit Jacob	2008-12-19
\|
*	* replace postfix ++ by prefix ++ wherever that makes sense in Eigen/	Benoit Jacob	2008-12-17
\| \| \| \| \|	* fix some "unused variable" warnings in the tests; there remains a libstdc++ "deprecated" warning which I haven't looked much into
*	* add .imag() function	Gael Guennebaud	2008-11-14
\| \| \| \| \| \|	* fix a very old bug in EigenSolver that I had completely forgotten (thanks to Timothy to refresh my mind) * fix doc of Matrix::Map
*	add EigenSolver::eigenvectors() method for non symmetric matrices.	Gael Guennebaud	2008-10-03
\| \| \| \| \| \|	However, for matrices larger than 5, it seems there is constantly a quite large error for a very few coefficients. I don't what's going on, but that's certainely not due to numerical issues only. (also note that the test with the pseudo eigenvectors fails the same way)
*	Fixes in Eigensolver:	Gael Guennebaud	2008-10-01
\| \| \| \| \| \| \| \|	* eigenvectors => pseudoEigenvectors * added pseudoEigenvalueMatrix * clear the documentation * added respective unit test Still missing: a proper eigenvectors() function.
*	if EIGEN_NICE_RANDOM is defined, the random functions will return numbers with	Benoit Jacob	2008-09-01
\| \| \| \| \| \|	few bits left of the comma and for floating-point types will never return zero. This replaces the custom functions in test/main.h, so one does not anymore need to think about that when writing tests.
*	* bug fixes in: Dot, generalized eigen problem, singular matrix detetection ↵	Gael Guennebaud	2008-08-23
\| \| \| \| \| \| \|	in Cholesky * fix all numerical instabilies in the unit tests, now all tests can be run 2000 times with almost zero failures.
*	Optimizations:	Gael Guennebaud	2008-08-01
\| \| \| \| \| \| \| \|	* faster matrix-matrix and matrix-vector products (especially for not aligned cases) * faster tridiagonalization (make it using our matrix-vector impl.) Others: * fix Flags of Map * split the test_product to two smaller ones
*	* Merge Extract and Part to the Part expression.	Gael Guennebaud	2008-07-21
\| \| \| \| \| \|	Renamed "MatrixBase::extract() const" to "MatrixBase::part() const" * Renamed static functions identity, zero, ones, random with an upper case first letter: Identity, Zero, Ones and Random.
*	* Added a generalized eigen solver for the selfadjoint case.	Gael Guennebaud	2008-06-14
\| \| \| \| \| \|	(as new members to SelfAdjointEigenSolver) The QR module now depends on Cholesky. * Fix Transpose to correctly preserve the *TriangularBit.
*	Added a Hessenberg decomposition class for both real and complex matrices.	Gael Guennebaud	2008-06-08
\| \| \| \| \| \| \|	This is the first step towards a non-selfadjoint eigen solver. Notes: - We might consider merging Tridiagonalization and Hessenberg toghether ? - Or we could factorize some code into a Householder class (could also be shared with QR)
*	update of the eigeinsolver unit test to check complex	Gael Guennebaud	2008-06-03

*	fix a couple of issues making the eigensolver test compile and run without ↵	Benoit Jacob	2008-06-02
\| \| \| \| \| \| \| \| \|	aborting on an assert. Had to fix a stupid bug in Block -- very strange we hadn't hit it before. However the test still fails.
*	* fix the QR module to use extract/part instead of the previous triangular stuff	Gael Guennebaud	2008-05-27
	* added qr and eigensolver tests * fix a compilation warning in Matrix copy constructor
