* Initial fixes for bug #85.Gravatar Hauke Heibel2010-10-25
| | | | | | | Renamed meta_{true|false} to {true|false}_type, meta_if to conditional, is_same_type to is_same, un{ref|pointer|const} to remove_{reference|pointer|const} and makeconst to add_const.

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

* Change skipU argument to computeU - this reverses the meaning.Gravatar Jitse Niesen2010-05-31
| | | | See "skipXxx / computeXxx parameters in Eigenvalues module" on mailing list.
* Guard with assert against using decomposition objects uninitialized.Gravatar Jitse Niesen2010-05-30
|
* 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().
* Use ReturnByValue mechanism for HessenbergDecomposition::matrixH().Gravatar Jitse Niesen2010-05-24
|
* Change return type of matrixH() method to HouseholderSequence.Gravatar Jitse Niesen2010-05-24
| | | | This method is a member of Tridiagonalization and HessenbergDecomposition.

| | | | | | | | * reduce scope of declarations * use that low = 0 and high = size-1 * rename some variables * rename hqr2_step2() to computeEigenvectors() * exploit that ei_isMuchSmallerThan takes absolute value of arguments

|
* * implement the corner() API change: new methods topLeftCorner() etcGravatar Benoit Jacob2010-04-22
| | | | | | | | * get rid of BlockReturnType: it was not needed, and code was not always using it consistently anyway * add topRows(), leftCols(), bottomRows(), rightCols() * add corners unit-test covering all of that * adapt docs, expand "porting from eigen 2 to 3" * adapt Eigen2Support
* - 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.
