* * the Upper->UpperTriangular changeGravatar Benoit Jacob2008-12-20
| | | | * finally get ei_add_test right
* * fix in IO.h, a useless copy was made because of assignment fromGravatar Benoit Jacob2008-12-18
| | | | | | | | | | | | | | | Derived to MatrixBase. * the optimization of eval() for Matrix now consists in a partial specialization of ei_eval, which returns a reference type for Matrix. No overriding of eval() in Matrix anymore. Consequence: careful, ei_eval is no longer guaranteed to give a plain matrix type! For that, use ei_plain_matrix_type, or the PlainMatrixType typedef. * so lots of changes to adapt to that everywhere. Hope this doesn't break (too much) MSVC compilation. * add code examples for the new image() stuff. * lower a bit the precision for floats in the unit tests as we were already doing some workarounds in inverse.cpp and we got some failed tests.
* * complete the change norm2->squaredNorm in PartialReduxGravatar Benoit Jacob2008-12-07
| | | | | | | * somehow the NICE_RANDOM stuff wasn't being used anymore and tests were sometimes failing again. Fixed by #including Eigen/Array instead of cherry-picking just Random.h. * little fixes in the unaligned assert page
* Use an aligned IOFormat in the docsGravatar Benoit Jacob2008-12-06

* norm2() renamed to squaredNorm(), kept as deprecated for now.Gravatar Benoit Jacob2008-11-03
|
* Big API change in Cholesky module:Gravatar Gael Guennebaud2008-10-13
| | | | | | | | | | | | | | | | * rename Cholesky to LLT * rename CholeskyWithoutSquareRoot to LDLT * rename MatrixBase::cholesky() to llt() * rename MatrixBase::choleskyNoSqrt() to ldlt() * make {LLT,LDLT}::solve() API consistent with other modules Note that we are going to keep a source compatibility untill the next beta release. E.g., the "old" Cholesky* classes, etc are still available for some time. To be clear, Eigen beta2 should be (hopefully) source compatible with beta1, and so beta2 will contain all the deprecated API of beta1. Those features marked as deprecated will be removed in beta3 (or in the final 2.0 if there is no beta 3 !). Also includes various updated in sparse Cholesky.

* * Added .all() and .any() members to PartialReduxGravatar Gael Guennebaud2008-08-20
| | | | | * Bug fixes in euler angle snippet, Assign and MapBase * Started a "quick start guide" (draft state)
* * doc improvements in Cwise and PartialRedux:Gravatar Benoit Jacob2008-08-19
| | | | | | | | | - 33 new snippets - unfuck doxygen output in Cwise (issues with function macros) - more see-also links from outside, making Cwise more discoverable * rename matrixNorm() to operatorNorm(). There are many matrix norms (the L2 is another one) but only one is called the operator norm. Risk of confusion with keyword operator is not too scary after all.
* last small fixes, this is alpha6, eigen2 is now ready for eigen1 apps toGravatar Benoit Jacob2008-08-12
| | | | port to.
* Complete LU documentationGravatar Benoit Jacob2008-08-11
|
* renamed inverseProduct => solveTriangularGravatar Gael Guennebaud2008-08-09
|
* * Rewrite the triangular solver so that we can take advantage of our ↵Gravatar Gael Guennebaud2008-07-26
| | | | | | | | | | | efficient matrix-vector products: => up to 6 times faster ! * Added DirectAccessBit to Part * Added an exemple of a cwise operator * Renamed perpendicular() => someOrthogonal() (geometry module) * Fix a weired bug in ei_constant_functor: the default copy constructor did not copy the imaginary part when the single member of the class is a complex...
* Add .perpendicular() function in Geometry module (adapted from Eigen1)Gravatar Gael Guennebaud2008-07-22
| | | | | | Documentation: * add an overview for each module. * add an example for .all() and Cwise::operator<
* * 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.
* Various documentation improvements, in particualr in Cholesky and Geometry ↵Gravatar Gael Guennebaud2008-07-20
| | | | | | module. Added doxygen groups for Matrix typedefs and the Geometry module
* Add cholesky's members to MatrixBaseGravatar Gael Guennebaud2008-07-19
| | | | Various documentation improvements including new snippets (AngleAxis and Cholesky)
* * big rework of Inverse.h:Gravatar Benoit Jacob2008-07-15
| | | | | | | | | | | - remove all invertibility checking, will be redundant with LU - general case: adapt to matrix storage order for better perf - size 4 case: handle corner cases without falling back to gen case. - rationalize with selectors instead of compile time if - add C-style computeInverse() * update inverse test. * in snippets, default cout precision to 3 decimal places * add some cmake module from kdelibs to support btl with cmake 2.4
* - many updates after Cwise changeGravatar Benoit Jacob2008-07-08
| | | | | - fix compilation in product.cpp with std::complex - fix bug in MatrixBase::operator!=
* * vectorize dot product, copying code from sum.Gravatar Benoit Jacob2008-06-24
| | | | | | | | | | | | | | | * make the conj functor vectorizable: it is just identity in real case, and complex doesn't use the vectorized path anyway. * fix bug in Block: a 3x1 block in a 4x4 matrix (all fixed-size) should not be vectorizable, since in fixed-size we are assuming the size to be a multiple of packet size. (Or would you prefer Vector3d to be flagged "packetaccess" even though no packet access is possible on vectors of that type?) * rename: isOrtho for vectors ---> isOrthogonal isOrtho for matrices ---> isUnitary * add normalize() * reimplement normalized with quotient1 functor
* fix building of examplesGravatar Gael Guennebaud2008-06-03

* many small fixes and documentation improvements,Gravatar Benoit Jacob2008-05-29
| | | | this should be alpha5.
* - remove Eval/EvalOMP (moving them to a disabled/ subdir in orderGravatar Benoit Jacob2008-03-31
| | | | | | | to preserve SVN history). They are made useless by the new ei_eval_unless_lazy. - introduce a generic Eval member typedef so one can do e.g. T t; U u; Product<T, U>::Eval m; m = t*u;
* Removed Column and Row in favor of BlockGravatar Gael Guennebaud2008-03-12

* Extended the comma initializer to support xpr on the right side:Gravatar Gael Guennebaud2008-03-08
| | | | | | Matrix3i mat; Vector2i vec(33,66); mat << vec.transpose(), 99, vec, Matrix2i::random();
* * Added support for a comma initializer: mat.block(i,j,2,2) << 1, 2, 3, 4;Gravatar Gael Guennebaud2008-03-08
| | | | | | | | | | If the number of coefficients does not match the matrix size, then an assertion is raised. No support for xpr on the right side for the moment. * Added support for assertion checking. This allows to test that an assertion is indeed raised when it should be. * Fixed a mistake in the CwiseUnary example.
* Patch by Gael Guennebaud: unify fixed-size and dynamic-size BlockGravatar Benoit Jacob2008-02-29
| | | | expressions, update documentation.
* alpha 3.1. in this commit:Gravatar Benoit Jacob2008-01-15
| | | | | | | | | - finally get the Eval stuff right. get back to having Eval as a subclass of Matrix with limited functionality, and then, add a typedef MatrixType to get the actual matrix type. - add swap(), findBiggestCoeff() - bugfix by Ramon in Transpose - new demo: doc/echelon.cpp
* documentation update for alpha 3Gravatar Benoit Jacob2008-01-13
|
* big improvement of the block-manipulation APIGravatar Benoit Jacob2008-01-13
| | | | | | | - reduction of sizeof(Block) for vector types - variants of block() and fixedBlock() for vector blocks - convenience methods start() and end() for vectors - convenience method corner() for matrices
* renaming:Gravatar Benoit Jacob2008-01-13
| | | | | | | Block -> FixedBlock DynBlock -> Block indeed, previous commit solves the main issue with DynBlock so is should now be the more commonly used one.
* rework Identity API: no longer restricted to square matricesGravatar Benoit Jacob2008-01-11
|
* -add set...() methods and their documentation; remove GenericGravatar Benoit Jacob2008-01-11
| | | | | | -use row-major traversal when the number of columns is fixed and the number of rows is dynamic -other minor changes
* Ready for alpha2 release.Gravatar Benoit Jacob2008-01-07
| | | | | | - complete documentation - add TODO - update copyright years
* - move: DerivedTraits becomes MatrixBase::TraitsGravatar Benoit Jacob2008-01-06
| | | | | | - the static constants are private again in the Derived classes - more documentation and code snippets - new isDiagonal() method
* - make MatrixBase and all expressions aware of their preferred traversal order.Gravatar Benoit Jacob2008-01-05
| | | | | | | Honor this preference in operator=. - add several methods to the API - rework API for diagonal matrices - add benchmarking code
* more documentation, 12 more code snippetsGravatar Benoit Jacob2008-01-03
|
* part 2 of the reorganization. Benefits/changes:Gravatar Benoit Jacob2007-12-28
| | | | | | 1) Eigen2 co-installable with Eigen1 without conflict, without affecting programs including either. 2) #include<Eigen/Core> without the .h without conflict with the Core/ directory 3) Uniformize coding style of the CMakeLists.
* matrix storage order can now also be row-dominant (choosable for each matrix ↵Gravatar Benoit Jacob2007-12-27
| | | | | | | separately) map() moves from MatrixBase to Matrix much more documentation/examples/snippets
* - rework the coefficients APIGravatar Benoit Jacob2007-12-24
| | | | | | | - make vectors use a separate loop unroller, so that copying a row-vector into a col-vector is now possible - add much more documentation - misc improvements
* everything works, make now runs doxygen once and only once, after allGravatar Benoit Jacob2007-12-21
| | | | the required files have been generated.
* now we also have a examples/ directory for self-contained examples,Gravatar Benoit Jacob2007-12-21
| | | | and this is already used to document DynBlock
* now cmake takes snippets of code, completes them into compilable sources, ↵Gravatar Benoit Jacob2007-12-21
| | | | | | builds them, executes them and stores their output in files.
