* Move IncompleteCholesky to official modulesGravatar Gael Guennebaud2015-10-08
|
* Doc: add link to doc of sparse solver conceptGravatar Gael Guennebaud2015-10-08
|
* Since there is no reason for evaluators to be nested by reference, let's ↵Gravatar Gael Guennebaud2015-09-02
| | | | remove the evaluator<>::nestedType indirection.
* Cleaning pass on evaluators: remove the useless and error prone ↵Gravatar Gael Guennebaud2015-09-02
| | | | evaluator<>::type indirection.
* Fix LSCG::solve with a sparse destination.Gravatar Gael Guennebaud2015-09-02
|
* Propagate precondition info to the iterative solver.Gravatar Gael Guennebaud2015-08-04
|
* Doc: explain perf and multithreading issues in sparse iterative solversGravatar Gael Guennebaud2015-06-26
|
* Optimize CG to enable faster spare row-major * dense vector products when ↵Gravatar Gael Guennebaud2015-06-25
| | | | the input matrix is complete (Upper|Lower) but column major.
* Clarify documentation of the tolerance and error returned in iterative solversGravatar Gael Guennebaud2015-06-25
|
* BiCGSTAB: set default guess to 0, and improve restart mechanism by ↵Gravatar Gael Guennebaud2015-06-05
| | | | recomputing the accurate residual.
* Fix bug #1010: m_isInitialized was improperly updatedGravatar Gael Guennebaud2015-05-07
|
* Fix compilation of iterative solvers with dense matricesGravatar Gael Guennebaud2015-03-09
|
* bug #963: make IncompleteLUT compatible with non-default storage index types.Gravatar Gael Guennebaud2015-03-09
|
* Rename LSCG to LeastSquaresConjugateGradientGravatar Gael Guennebaud2015-03-05
|
* Really use zero guess in ConjugateGradients::solve as documentedGravatar Jan Blechta2015-02-18
| | | | and expected for consistency with other methods.
* Add a CG-based solver for rectangular least-square problems (bug #975).Gravatar Gael Guennebaud2015-03-04
|
* bug #897: fix regression in BiCGSTAB(mat) ctor (an all other iterative solvers).Gravatar Gael Guennebaud2015-02-16
| | | | Add respective regression unit test.
* Remove deprecated usage of expr::Index.Gravatar Gael Guennebaud2015-02-16
|
* Fix many long to int conversion warnings:Gravatar Gael Guennebaud2015-02-16
| | | | | | - fix usage of Index (API) versus StorageIndex (when multiple indexes are stored) - use StorageIndex(val) when the input has already been check - use internal::convert_index<StorageIndex>(val) when val is potentially unsafe (directly comes from user input)
* Index refactoring: StorageIndex must be used for storage only (and locally ↵Gravatar Gael Guennebaud2015-02-13
| | | | when it make sense). In all other cases use the global Index type.
* Merge Index-refactoring branch with default, fix PastixSupport, remove some ↵Gravatar Gael Guennebaud2015-02-13
|\ | | | | | | useless typedefs
| * Fix bug #733: step by step solving is not a good example for solveWithGuessGravatar Jan Blechta2015-02-10
| |
| * Allows Lower|Upper as a template argument of CG and MINRES: in this case the ↵Gravatar Gael Guennebaud2015-02-10
| | | | | | | | full matrix will be considered.
| * bug #897: makes iterative sparse solvers use a Ref<SparseMatrix> instead of ↵Gravatar Gael Guennebaud2015-02-09
| | | | | | | | a SparseMatrix pointer. This fixes usage of iterative solvers with a Map<SparseMatrix>.
* | bug #877, bug #572: Introduce a global Index typedef. Rename Sparse*::Index ↵Gravatar Christoph Hertzberg2014-12-04
|/ | | | to StorageIndex, make Dense*::StorageIndex an alias to DenseIndex. Overall this commit gets rid of all Index conversion warnings.
* bug #889: fix protected typedefGravatar Gael Guennebaud2014-10-08
|
* Make constructors explicit if they could lead to unintended implicit conversionGravatar Christoph Hertzberg2014-09-23
|
* Fix typos in docs for IterativeLinearSolvers moduleGravatar Jitse Niesen2014-09-21
|
* Fix copy-and-paste typo in SolveWithGuess assignmentGravatar Jitse Niesen2014-09-21
| | | | This fixes compilation of code snippets in BiCGSTAB docs.
* Remove deprecated code not used by evaluatorsGravatar Gael Guennebaud2014-09-18
|
* Factorize solveWithGuess in IterativeSolverBaseGravatar Gael Guennebaud2014-09-01
|
* Make IncompleteLUT use SparseSolverBase.Gravatar Gael Guennebaud2014-09-01
|
* Refactoring of sparse solvers through a SparseSolverBase class and usage of ↵Gravatar Gael Guennebaud2014-09-01
| | | | the Solve<> expression. Introduce a SolveWithGuess expression on top of Solve.
* Do not apply the preconditioner before starting the iterations as this might ↵Gravatar Gael Guennebaud2014-08-21
| | | | destroy a very good initial guess.
* Fix regeression in bicgstab: the threshold used to detect the need for a ↵Gravatar Gael Guennebaud2014-07-01
| | | | restart was much too large.
* Fix Jacobi preconditioner with zero diagonal entriesGravatar Gael Guennebaud2014-06-17
|
* Fix bug #688: make it clearer that CG is for both dense and sparse matrices.Gravatar Gael Guennebaud2013-10-28
|
* Fix bug #674: typo in documentation example for BiCGSTAB. They are now ↵Gravatar Gael Guennebaud2013-10-16
| | | | proper snippet files.
* IncompleteLUT should not raise an assert in compute if factorize failed.Gravatar Gael Guennebaud2013-07-17
|
