| | | | | | | | | | | | disabled. All unimplemented assignment operators have been removed.
| * Added to possibility to compile unit tests at maximum warning level.Gravatar Hauke Heibel2009-12-12
| | | | | | | | Silenced (amongst others) many conversion related warnings.

| * precision ---> dummy_precisionGravatar Benoit Jacob2009-11-26

* | Big refactoring/cleaning in the spasre module withGravatar Gael Guennebaud2009-11-18
| | | | | | | | | | | | in particular the addition of a selfadjointView, and the extension of triangularView. The rest is cleaning and does not change/extend the API.
* | more ET refactoring:Gravatar Gael Guennebaud2009-11-17
| | | | | | | | | | * extend Cwise for multiple storage base class * a lot of cleaning in the Sparse module
* | Experiment the ET refactoring on Transpose for Dense and Sparse storages.Gravatar Gael Guennebaud2009-11-16
|/ | | | All tests work fine.
* add a SparseNestByValue expression and fix issue in sparse adjoint evaluationGravatar Gael Guennebaud2009-07-13
|
* fixes a segfaultGravatar Gael Guennebaud2009-07-05

* SparseMatrix::resize() always resets the matrix to an empty oneGravatar Gael Guennebaud2009-06-08
|
* remove sentence "Eigen itself is part of the KDE project."Gravatar Benoit Jacob2009-05-22
| | | | it never made very precise sense. but now does it still make any?
* * optimize sum() for sparse matrices and vectorsGravatar Gael Guennebaud2009-05-19
| | | | * fix the row()/col() functions of some InnerVector
* fix realloc when initial size was 0 (bug reported by Jens Mueller)Gravatar Gael Guennebaud2009-05-07
|
* new simplified API to fill sparse matrices (the old functions areGravatar Gael Guennebaud2009-05-04
| | | | | | | | | | | | deprecated). Basically there are now only 2 functions to set a coefficient: 1) mat.coeffRef(row,col) = value; 2) mat.insert(row,col) = value; coeffRef has no limitation, insert assumes the coeff has not already been set, and raises an assert otherwise. In addition I added a much lower level, but more efficient filling mechanism for internal use only.
* sparse module: new API proposal for triangular solves and experimentalGravatar Gael Guennebaud2009-04-05
| | | | solver support with a sparse matrix as the rhs.
* fix Taucs support (it appears Taucs does not return sorted matrices)Gravatar Gael Guennebaud2009-03-26
|
* various minor fixes in Sparse moduleGravatar Gael Guennebaud2009-02-10
|
* - add diagonal * sparse product as an expressionGravatar Gael Guennebaud2009-02-09
| | | | | - split sparse_basic unit test - various fixes in sparse module
* fix MatrixNase::fillrand bugGravatar Gael Guennebaud2009-01-26
|
* sparse module: makes -= and += operator workingGravatar Gael Guennebaud2009-01-23
| | | | | | Question 1: why are *=scalar and /=scalar working right away ? Same weirdness in DynamicSparseMatrix where operators += and -= work wihout having to redefine them ???
* * fix compilation with gcc 3.4Gravatar Gael Guennebaud2009-01-23
| | | | * add an option to disable Qt testing
* sparse module:Gravatar Gael Guennebaud2009-01-21
| | | | | * add row(i), col(i) functions * add prune() function to remove small coefficients

|
* Sparse module: bugfix in SparseMatrix::resize(), now the indices areGravatar Gael Guennebaud2009-01-15
| | | | correctly initialized to 0.
* Sparse module:Gravatar Gael Guennebaud2009-01-15
| | | | | | * add a MappedSparseMatrix class (like Eigen::Map but for sparse matrices) * rename SparseArray to CompressedStorage
* Sparse module:Gravatar Gael Guennebaud2009-01-14
| | | | | * improved performance of mat*=scalar * bug fix in cwise*
* Add support for sparse * dense and dense * sparse matrix/vector productsGravatar Gael Guennebaud2009-01-14

* Big rewrite in the Sparse module: SparseMatrixBase no longer inherits ↵Gravatar Gael Guennebaud2009-01-14
| | | | | | | | | | | | | | MatrixBase. That means a lot of features which were available for sparse matrices via the dense (and super slow) implemention are no longer available. All features which make sense for sparse matrices (aka can be implemented efficiently) will be implemented soon, but don't expect to see an API as rich as for the dense path. Other changes: * no block(), row(), col() anymore. * instead use .innerVector() to get a col or row vector of a matrix. * .segment(), start(), end() will be back soon, not sure for block() * faster cwise product
* * suppressed some minor warningsGravatar Kenneth Frank Riddile2009-01-06
|
* Added a SparseVector class (not tested yet)Gravatar Gael Guennebaud2009-01-02
|
* Sparse module:Gravatar Gael Guennebaud2008-12-27
| | | | | | * enable complex support for the CHOLMOD LLT backend using CHOLMOD's triangular solver * quick fix for complex support in SparseLLT::solve
* more MSVC cmake fixesGravatar Gael Guennebaud2008-12-17
|
* fix bad typos, thanks to Kenneth RiddileGravatar Benoit Jacob2008-12-17
|
* * replace postfix ++ by prefix ++ wherever that makes sense in Eigen/Gravatar Benoit Jacob2008-12-17
| | | | | * fix some "unused variable" warnings in the tests; there remains a libstdc++ "deprecated" warning which I haven't looked much into
* Sparse module: add a more flexible SparseMatrix::fillrand() functionGravatar Gael Guennebaud2008-12-11
| | | | | which allows to fill a matrix with random inner coordinates (makes sense only when a very few coeffs are inserted per col/row)
* Several improvements in sparse module:Gravatar Gael Guennebaud2008-11-05
| | | | | | | | | * add a LDL^T factorization with solver using code from T. Davis's LDL library (LPGL2.1+) * various bug fixes in trianfular solver, matrix product, etc. * improve cmake files for the supported libraries * split the sparse unit test * etc.
* * sparse LU: add extraction of L,U,P, and Q, as well as determinantGravatar Gael Guennebaud2008-10-20
| | | | | for both backends. * extended a bit the sparse unit tests
* sparse module: add preliminary support for direct sparse LU solverGravatar Gael Guennebaud2008-10-19
| | | | | using SuperLU. Calling SuperLU was very painful, but it was worth it, it seems to be damn fast !
* sparse module: much much faster transposition codeGravatar Gael Guennebaud2008-10-18
|
* Sparse module: add experimental support for TAUCS and CHOLMOD with:Gravatar Gael Guennebaud2008-10-05
| | | | | * bidirectionnal mapping * full cholesky factorization
* Sparse module:Gravatar Gael Guennebaud2008-10-04
| | | | | | | | | | * several fixes (transpose, matrix product, etc...) * Added a basic cholesky factorization * Added a low level hybrid dense/sparse vector class to help writing code involving intensive read/write in a fixed vector. It is currently used to implement the matrix product itself as well as in the Cholesky factorization.
* resurrected sparse triangular solverGravatar Gael Guennebaud2008-09-02

* Extended sparse unit-test: nested blocks and InnerIterators.Gravatar Daniel Gomez Ferro2008-09-02
| | | | | Block specialization for sparse matrices. InnerIterators for Blocks and fixes in CoreIterators.
