| | | | | Add an assert to guard against using eigenvalues that have not converged. Add call to info() in tutorial example to cover non-convergence.

* Document enums in Constants.h (bug #248).Gravatar Jitse Niesen2011-05-03
| | | | | | 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.
* Document (non)sorting of eigenvalues.Gravatar Jitse Niesen2011-02-27
| | | | | Also, update docs for (Generalized)SelfAdjointEigenSolver to reflect that these two classes were split apart.

| | | | | - all what's not in unsupported/ is considered stable API (except internal stuff e.g. expression templates).

| | | | | | | | | | * 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.

* the Index types change.Gravatar Benoit Jacob2010-05-30
| | | | As discussed on the list (too long to explain here).
* Update eigenvalues() and operatorNorm() methods in MatrixBase.Gravatar Jitse Niesen2010-05-24
| | | | | | | | * 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
* Return matrices by constant reference where possible.Gravatar Jitse Niesen2010-05-24
| | | | | | | This changes the return type of: * eigenvectors() and eigenvalues() in ComplexEigenSolver * eigenvalues() in EigenSolver * eigenvectors() and eigenvalues() in SelfAdjointEigenSolver
* Replace local variables by member variables in compute() methods.Gravatar Jitse Niesen2010-05-24
| | | | | | | This is to avoid dynamic memory allocations in the compute() methods of ComplexEigenSolver, EigenSolver, and SelfAdjointEigenSolver where possible. As a result, Tridiagonalization::decomposeInPlace() is no longer used. Biggest remaining issue is the allocation in HouseholderSequence::evalTo().
* Document SelfAdjointEigenSolver and add examples.Gravatar Jitse Niesen2010-05-04

* - Added problem size constructor to decompositions that did not have one. It ↵Gravatar Adolfo Rodriguez Tsouroukdissian2010-04-21
| | | | | | | | | | | 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.

* Propagate all five matrix template parameters to members and temporaries of ↵Gravatar Adolfo Rodriguez Tsouroukdissian2010-03-08
| | | | | | | decomposition classes. One particular advantage of this is that decomposing matrices with max sizes known at compile time will not allocate. NOTE: The ComplexEigenSolver class currently _does_ allocate (line 135 of Eigenvalues/ComplexEigenSolver.h), but the reason appears to be in the implementation of matrix-matrix products, and not in the decomposition itself. The nomalloc unit test has been extended to verify that decompositions do not allocate when max sizes are specified. There are currently two workarounds to prevent the test from failing (see comments in test/nomalloc.cpp), both of which are related to matrix products that allocate on the stack.
* Renamed PlainMatrixType to PlainObject (Array != Matrix).Gravatar Hauke Heibel2010-02-20
| | | | Renamed ReturnByValue::ReturnMatrixType ReturnByValue::ReturnType (again, Array != Matrix).
* remove the Triangular suffix to Upper, Lower, UnitLower, etc,Gravatar Gael Guennebaud2010-01-07
| | | | and remove the respective bit flags
* Another big refactoring change:Gravatar Gael Guennebaud2009-11-18
| | | | | | * 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
