* 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 vectorization of sqrt for floatGravatar Gael Guennebaud2009-03-27

* add SSE2 versions of sin, cos, log, exp using code from JulienGravatar Gael Guennebaud2009-03-25
| | | | | | | | Pommier. They are for float only, and they return exactly the same result as the standard versions in about 90% of the cases. Otherwise the max error is below 1e-7. However, for very large values (>1e3) the accuracy of sin and cos slighlty decrease. They are about 3 or 4 times faster than 4 calls to their respective standard versions. So, is it ok to enable them by default in their respective functors ?
* add vectorization of unary operator-() (the AltiVec version is probablyGravatar Gael Guennebaud2009-03-20

* add the vectorization of absGravatar Gael Guennebaud2009-03-09

* big addons:Gravatar Gael Guennebaud2009-03-05
| | | | | | | | | | | * add Homogeneous expression for vector and set of vectors (aka matrix) => the next step will be to overload operator* * add homogeneous normalization (again for vector and set of vectors) * add a Replicate expression (with uni-directional replication facilities) => for all of them I'll add examples once we agree on the API * fix gcc-4.4 warnings * rename reverse.cpp array_reverse.cpp
* * exit Sum.h, exit Prod.h, welcome vectorization of redux() !Gravatar Gael Guennebaud2009-02-12
| | | | * add vectorization for minCoeff and maxCoeff
* * add ei_predux_mul internal functionGravatar Gael Guennebaud2009-02-10
| | | | * apply Ricard Marxer's prod() patch with fixes for the vectorized path
* Add vectorization of Reverse (was more tricky than I thought) andGravatar Gael Guennebaud2009-02-06

* * bugfix in SolveTriangular found by Timothy Hunter (did not compiled for ↵Gravatar Gael Guennebaud2008-08-22
| | | | | | | | very small fixed size matrices) * bugfix in Dot unroller * added special random generator for the unit tests and reduced the tolerance threshold by an order of magnitude this fixes issues with sum.cpp but other tests still failed sometimes, this have to be carefully checked...
* disable the vectorization of div for AltiVecGravatar Gael Guennebaud2008-08-21
