|
* Replace assert() by eigen_assert() (fixes bug #548).Gravatar Jitse Niesen2013-02-02
|
* Automatic relicensing to MPL2 using Keirs script. Manual fixup follows.Gravatar Benoit Jacob2012-07-13
|
* Get rid of include directives inside namespace blocks (bug #339).Gravatar Jitse Niesen2012-04-15
|
* Renamed cleantype to remove_all since it is close to ↵Gravatar Hauke Heibel2010-10-26
| | | | remove_{const|pointer|reference}.
* bug #86 : use internal:: namespace instead of ei_ prefixGravatar Benoit Jacob2010-10-25
|
* add support for determinant on empty matrixGravatar Gael Guennebaud2010-07-19
|
* Added a missing inline hints.Gravatar Hauke Heibel2010-03-03
| | | | Removed a useless Nested temporary.
* fix a couple of ICE with gcc 4.0.1Gravatar Gael Guennebaud2010-02-12
|
* remove the Triangular suffix to Upper, Lower, UnitLower, etc,Gravatar Gael Guennebaud2010-01-07
| | | | and remove the respective bit flags
* * 4x4 inverse: revert to cofactors methodGravatar Benoit Jacob2009-12-09
| | | | | | | * inverse tests: use createRandomMatrixOfRank, use more strict precision * tests: createRandomMatrixOfRank: support 1x1 matrices * determinant: nest the xpr * Minor: add comment
* big huge changes, so i dont remember everything.Gravatar Benoit Jacob2009-10-28
| | | | | | | | | | * 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
* fixes in determinant and homogeneousGravatar Gael Guennebaud2009-08-06

* 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?
* add partial-pivoting LU decompositionGravatar Benoit Jacob2009-05-13
| | | | | | the name 'PartialLU' is not meant to be definitive! make inverse() and determinant() use it, so it's *almost* considered well tested.
* Update e-mail addressGravatar Benoit Jacob2008-11-24
|
* * fix bug in SwapWrapper : store the wrapped expression by referenceGravatar Benoit Jacob2008-08-09
| | | | | | * optimize setIdentity: when the matrix is large enough it is better to setZero() and overwrite the diagonal * start of LU solver, disabled for now
* forgot to remove that old codeGravatar Benoit Jacob2008-08-07
|
* - add kernel computation using the triangular solverGravatar Benoit Jacob2008-08-07
| | | | | | - take advantage of the fact that our LU dec sorts the eigenvalues of U in decreasing order - add meta selector in determinant
* * LU decomposition, supporting all rectangular matrices, with fullGravatar Benoit Jacob2008-08-04
| | | | | | | | | | pivoting for better numerical stability. For now the only application is determinant. * New determinant unit-test. * Disable most of Swap.h for now as it makes LU fail (mysterious). Anyway Swap needs a big overhaul as proposed on IRC. * Remnants of old class Inverse removed. * Some warnings fixed.
* big changes in Doxygen configuration; work around bug with doxygen parsing ofGravatar Benoit Jacob2008-06-02
| | | | | initialized enum values showing the last word the initializer instead of the actual enum value's name; add some more docs.
* - introduce Part and Extract classes, splitting and extending the formerGravatar Benoit Jacob2008-05-27
| | | | | | | | | | Triangular class - full meta-unrolling in Part - move inverseProduct() to MatrixBase - compilation fix in ProductWIP: introduce a meta-selector to only do direct access on types that support it. - phase out the old Product, remove the WIP_DIRTY stuff. - misc renaming and fixes
* Added Triangular expression to extract upper or lower (strictly or not)Gravatar Gael Guennebaud2008-04-26
| | | | | | | | | | | part of a matrix. Triangular also provide an optimised method for forward and backward substitution. Further optimizations regarding assignments and products might come later. Updated determinant() to take into account triangular matrices. Started the QR module with a QR decompostion algorithm. Help needed to build a QR algorithm (eigen solver) based on it.
* fix a bug in determinant of 4x4 matrices and a small type issue in InverseGravatar Gael Guennebaud2008-04-26
|
* - optimized determinant calculations for small matrices (size <= 4)Gravatar Benoit Jacob2008-04-14
(only 30 muls for size 4) - rework the matrix inversion: now using cofactor technique for size<=3, so the ugly unrolling is only used for size 4 anymore, and even there I'm looking to get rid of it.
