* add reconstructedMatrix() to LLT, and LUsGravatar Gael Guennebaud2010-02-24
| | | | | => they show that some improvements have still to be done for permutations, tr*tr, trapezoidal matrices

* LDLT:Gravatar Benoit Jacob2010-02-23
| | | | | * fix bug thanks to Ben Goodrich: we were terminating at the wrong place, leaving some matrix coefficients with wrong values. * don't use Higham's formula here: we're not trying to be rank-revealing.
* compilation fix in ldlt() for non matrix typesGravatar Gael Guennebaud2010-02-21

* Renamed PlainMatrixType to PlainObject (Array != Matrix).Gravatar Hauke Heibel2010-02-20
| | | | Renamed ReturnByValue::ReturnMatrixType ReturnByValue::ReturnType (again, Array != Matrix).
* * move dummy_precision and epsilon to NumTraitsGravatar Gael Guennebaud2010-02-10
| | | | * make NumTraits inherits std::numeric_limits
* Introduced NestParentByRefBit and NestByRefBit - this should fix temporaries ↵Gravatar Hauke Heibel2010-02-06

* | 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
* last round of changes, mainly to return derived types instead of base types, ↵Gravatar Benoit Jacob2009-11-09

* 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
* * Introduce make targets btest (build tests), blas (build blas lib), demos ↵Gravatar Benoit Jacob2009-09-27
| | | | | | | | | (build demos). * remove EIGEN_BUILD_TESTS and siblings * add summary at the end of cmake run, hopefully not too verbose * fix build of quaternion demo * kill remnants of old binary library option
* Adaptions from .lazy() towards .noalias().Gravatar Hauke Heibel2009-08-31
| | | | Added missing casts.

* More Cholesky fixes.Gravatar Benoit Jacob2009-04-01
| | | | | | | | | * Cholesky decs are NOT rank revealing so remove all the rank/isPositiveDefinite etc stuff. * fix bug in LLT: s/return/continue/ * introduce machine_epsilon constants, they are actually needed for Higman's formula determining the cutoff in Cholesky. Btw fix the page reference to his book (chat with Keir). * solve methods always return true, since this isn't a rank revealing dec. Actually... they already did always return true!! Now it's explicit. * updated dox and unit-test

* Many improvements in LLT and LDLT:Gravatar Benoit Jacob2009-03-30
