9c0aa81fbf bug #854: fix numerical issue in SelfAdjointEigenSolver::computeDirect for 3x3 matrices. The tolerance to detect stable cross products was too optimistic. 
Add respective unit tests.

324e7e8fc9 Removed the deprecated EIGEN2_SUPPORT, as previously announced. A compilation error is raised, if this compile-switch is defined. The documentation references to the corresponding pages from Eigen3.2 now. Also, the Eigen2 testsuite has been removed. 2014-07-01 16:58:11 +02:00

a76fbbf397 Fix bug #314: 
- remove most of the metaprogramming kung fu in MathFunctions.h (only keep functions that differs from the std)
- remove the overloads for array expression that were in the std namespace

a594ac3966 Allow for more iterations in SelfAdjointEigenSolver (bug #354). 
Add an assert to guard against using eigenvalues that have not converged.
Add call to info() in tutorial example to cover non-convergence.

42e2578ef9 the min/max macros to detect unprotected min/max were undefined by some std header, 
so let's declare them after and do the respective fixes ;)

a96c849c20 Document enums in Constants.h (bug #248). 
To get the links to work, I also had to document the Eigen namespace.
Unfortunately, this means that the word Eigen is linked whenever it appears
in the docs.

a8f5ef9388 Document (non)sorting of eigenvalues. 
Also, update docs for (Generalized)SelfAdjointEigenSolver to reflect that these
two classes were split apart.

e5de9e5226 Remove \nonstable yet. The stability rules for Eigen3 are much simpler: 
- all what's not in unsupported/ is considered stable API
    (except internal stuff e.g. expression templates).

469382407c * Make HouseholderSequence::evalTo works in place 
* Clean a bit the Triadiagonalization making sure it the inplace
  function really works inplace ;), and that only the lower
   triangular part of the matrix is referenced.
* Remove the Tridiagonalization member object of SelfAdjointEigenSolver
  exploiting the in place capability of HouseholdeSequence.
* Update unit test to check SelfAdjointEigenSolver only consider
  the lower triangular part.
