e7d809d434 Update eigenvalues() and operatorNorm() methods in MatrixBase.
* use SelfAdjointView instead of Eigen2's SelfAdjoint flag.
* add tests and documentation.
* allow eigenvalues() for non-selfadjoint matrices.
* they no longer depend only on SelfAdjointEigenSolver, so move them to
  a separate file

28dde19e40 - Added problem size constructor to decompositions that did not have one. It preallocates member data structures.
- Updated unit tests to check above constructor.
- In the compute() method of decompositions: Made temporary matrices/vectors class members to avoid heap allocations during compute() (when dynamic matrices are used, of course).

These  changes can speed up decomposition computation time when a solver instance is used to solve multiple same-sized problems. An added benefit is that the compute() method can now be invoked in contexts were heap allocations are forbidden, such as in real-time control loops.

CAVEAT: Not all of the decompositions in the Eigenvalues module have a heap-allocation-free compute() method. A future patch may address this issue, but some required API changes need to be incorporated first.

d91ffffc37 Allow ComplexEigenSolver and ComplexSchur to work with real matrices.
Add a test which covers this case.

945cbc3bc6 Add test for issue #75 (Hessenberg of 1x1 matrix).
Also remove an superfluous #include in matrixExponential test.

e3d890bc5a Another big refactoring change:
* add a new Eigen2Support module including Cwise, Flagged, and some other deprecated stuff
* add a few cwiseXxx functions
* adapt a few modules to use cwiseXxx instead of the .cwise() prefix

* remove a ctor in QuaternionBase as it gives a strange error with GCC 4.4.2.

daa4574a43 Add regression test for issue #66 (ComplexSchur of zero matrix). 2009-11-05 03:46:18 +00:00

2840ac7e94 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

6c1b91678b kill ei_add_test_multi. Now the macro ei_add_test does all that automatically, by parsing the source file. No risk anymore to specify the wrong number of tests! Also, introduce CALL_SUBTESTX for X=1..10 that allows to port existing code much quicker. And port already the product* and eigensolver* files. 2009-10-19 14:40:35 -04:00

a54b99fa72 move eigen values related stuff of the QR module to a new EigenSolver module.
- perhaps we can find a better name ?
- note that the QR module still includes the EigenSolver module for compatibility

5b8ffa4d46 clean a bit the previous commit which came from a patch queue,
and since it was my first try of the patch queue feature I did not
managed to apply it with a good commit message, so here you go:
* Add a ComplexSchur decomposition class built on top of HessenbergDecomposition
* Add a ComplexEigenSolver built on top of ComplexSchur
There are still a couple of FIXME but at least they work for any reasonable matrices,
still have to extend the unit tests to stress them with nasty matrices...
