* Set of fixes and workaround to make sun studio more happy.Gravatar Gael Guennebaud2009-07-10
| | | | Still remains the problem of alignment and vectorization.
* * rename PartialRedux to VectorwiseOpGravatar Gael Guennebaud2009-06-10
| | | | * add VectorwiseOp's +, -, +=, -= operators
* 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?
* fix msvc warnings (useful ones again) reported by gael on CDashGravatar Benoit Jacob2009-01-26
|
* add partial count redux (adapted patch from Ricard Marxer)Gravatar Gael Guennebaud2009-01-24
|
* add lpNorm<p>() method to MatrixBase, implemented in Array module, withGravatar Benoit Jacob2008-11-03
| | | | specializations for cases p=1,2,Eigen::Infinity.
* Add coeff-wise comparisons to scalar operators. You can now write:Gravatar Gael Guennebaud2008-09-03
| | | | | | mat.cwise() < 2 instead of: mat.cwise() < MatrixType::Constant(mat.rows(), mat.cols(), 2)
* Add a Select expression in the Array module which mimics a coeff-wise ?: ↵Gravatar Gael Guennebaud2008-09-03
| | | | | | | | operator. Example: mat = (mat.cwise().abs().cwise() < Ones()).select(0,mat); replaces all small values by 0. (the scalar version is "s = abs(s)<1 ? 0 : s")
* if EIGEN_NICE_RANDOM is defined, the random functions will return numbers withGravatar Benoit Jacob2008-09-01
| | | | | | few bits left of the comma and for floating-point types will never return zero. This replaces the custom functions in test/main.h, so one does not anymore need to think about that when writing tests.
* * bug fixes in: Dot, generalized eigen problem, singular matrix detetection ↵Gravatar Gael Guennebaud2008-08-23
| | | | | | | in Cholesky * fix all numerical instabilies in the unit tests, now all tests can be run 2000 times with almost zero failures.
* * Merge Extract and Part to the Part expression.Gravatar Gael Guennebaud2008-07-21
| | | | | | Renamed "MatrixBase::extract() const" to "MatrixBase::part() const" * Renamed static functions identity, zero, ones, random with an upper case first letter: Identity, Zero, Ones and Random.
* Added MatrixBase::Unit*() static function to easily create unit/basis vectors.Gravatar Gael Guennebaud2008-07-19
| | | | | | | Removed EulerAngles, addes typdefs for Quaternion and AngleAxis, and added automatic conversions from Quaternion/AngleAxis to Matrix3 such that: Matrix3f m = AngleAxisf(0.2,Vector3f::UnitX) * AngleAxisf(0.2,Vector3f::UnitY); just works.
* the big Array/Cwise rework as discussed on the mailing list. The new APIGravatar Benoit Jacob2008-07-08
| | | | can be seen in Eigen/src/Core/Cwise.h.
* forgot to add the unit test array.cppGravatar Gael Guennebaud2008-06-21
