* * fix the QR module to use extract/part instead of the previous triangular stuffGravatar Gael Guennebaud2008-05-27
| | | | | * added qr and eigensolver tests * fix a compilation warning in Matrix copy constructor
* - 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
* restored the product testGravatar Gael Guennebaud2008-05-22
|
* update of the testing framework:Gravatar Gael Guennebaud2008-05-22
| | | | | replaced the QTestLib framework my custom macros and a (optional) custom script to run the tests from ctest.
* updated product test to carefully test all scalar typesGravatar Gael Guennebaud2008-05-12
| | | | and fix an issue in the triangular test
* * Patch by Konstantinos Margaritis: AltiVec vectorization.Gravatar Benoit Jacob2008-05-03
| | | | * Fix several warnings, temporarily disable determinant test.
* added a test for triangular matricesGravatar Gael Guennebaud2008-05-02
|

| | | | | * updated Cholesky to support complex * correct result_type for abs and abs2 functors
* added Cholesky moduleGravatar Gael Guennebaud2008-04-27
|
* Fixed a couple of issues introduced in previous commits.Gravatar Gael Guennebaud2008-04-26
| | | | Added a test for Triangular.
* added a tough test to check the determinant that currently failsGravatar Gael Guennebaud2008-04-25
|
* - cleaner use of OpenMP (no code duplication anymore)Gravatar Benoit Jacob2008-04-11
| | | | | | | | | | | | | | using a macro and _Pragma. - use OpenMP also in cacheOptimalProduct and in the vectorized paths as well - kill the vector assignment unroller. implement in operator= the logic for assigning a row-vector in a col-vector. - CMakeLists support for building tests/examples with -fopenmp and/or -msse2 - updates in bench/, especially replace identity() by ones() which prevents underflows from perturbing bench results.
* Added initial experimental support for explicit vectorization.Gravatar Gael Guennebaud2008-04-09
| | | | | | | | | | | | | Currently only the following platform/operations are supported: - SSE2 compatible architecture - compiler compatible with intel's SSE2 intrinsics - float, double and int data types - fixed size matrices with a storage major dimension multiple of 4 (or 2 for double) - scalar-matrix product, component wise: +,-,*,min,max - matrix-matrix product only if the left matrix is vectorizable and column major or the right matrix is vectorizable and row major, e.g.: a.transpose() * b is not vectorized with the default column major storage. To use it you must define EIGEN_VECTORIZE and EIGEN_INTEL_PLATFORM.
* * make use of the EvalBeforeNestingBit and EvalBeforeAssigningBitGravatar Gael Guennebaud2008-04-05
| | | | | | | | | | | in ei_xpr_copy and operator=, respectively. * added Matrix::lazyAssign() when EvalBeforeAssigningBit must be skipped (mainly internal use only) * all expressions are now stored by const reference * added Temporary xpr: .temporary() must be called on any temporary expression not directly returned by a function (mainly internal use only) * moved all functors in the Functors.h header * added some preliminaries stuff for the explicit vectorization
* * added cwise comparisonsGravatar Gael Guennebaud2008-04-03
| | | | | | | * added "all" and "any" special redux operators * added support bool matrices * added support for cost model of STL functors via ei_functor_traits (By default ei_functor_traits query the functor member Cost)
* -new: recursive costs system, useful to determine automaticallyGravatar Benoit Jacob2008-04-03
| | | | | | | | when to evaluate arguments and when to meta-unroll. -use it in Product to determine when to eval args. not yet used to determine when to unroll. for now, not used anywhere else but that'll follow. -fix badness of my last commit
* Make use of the LazyBit, introduce .lazy(), remove lazyProduct.Gravatar Benoit Jacob2008-03-31
|
* * introducte recursive Flags system for the expressionsGravatar Benoit Jacob2008-03-30
| | | | | | -- currently 3 flags: RowMajor, Lazy and Large -- only RowMajor actually used for now * many minor improvements
* * add Gael copyright lines on 2 more filesGravatar Benoit Jacob2008-03-26
| | | | | | | * macro renaming: EIGEN_NDEBUG becomes EIGEN_NO_DEBUG as this is much better (and similar to Qt) and EIGEN_CUSTOM_ASSERT becomes EIGEN_USE_CUSTOM_ASSERT * protect Core header by a EIGEN_CORE_H
* small fix of VERIFY_ASSERT in debug modeGravatar Gael Guennebaud2008-03-13
|
* a lot of renamingGravatar Benoit Jacob2008-03-13
| | | | | | | | internal classes: AaBb -> ei_aa_bb IntAtRunTimeIfDynamic -> ei_int_if_dynamic unify UNROLLING_LIMIT (there was no reason to have operator= use a higher limit) etc...
* fixed an issue with VERIFY_ASSERTGravatar Gael Guennebaud2008-03-12
|
* Removed Column and Row in favor of BlockGravatar Gael Guennebaud2008-03-12
|
* generalized ei_traits<>.Gravatar Benoit Jacob2008-03-12
| | | | | | Finally the importing macro is named EIGEN_BASIC_PUBLIC_INTERFACE because it does not only import the ei_traits, it also makes the base class a friend, etc.
* big change: MatrixBase only takes one template parameter "Derived", theGravatar Benoit Jacob2008-03-10
| | | | | | template parameter "Scalar" is removed. This is achieved by introducting a template <typename Derived> struct Scalar to achieve a forward-declaration of the Scalar typedefs.
* 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.
* * coefficient wise operators are more generic, with controllable result type.Gravatar Gael Guennebaud2008-03-06
| | | | | | - compatible with current STL's functors as well as with the extention proposal (TR1) * thanks to the above, Cast and ScalarMultiple have been removed * benchmark_suite is more flexible (compiler and matrix size)
* * Fix a compilation issue with large fixed-size matrices: the unrollers ↵Gravatar Gael Guennebaud2008-03-05
| | | | | | were always instanciated. * the unrolling limits are configurable at compile time.
* Removed trailling spaces.Gravatar Gael Guennebaud2008-03-03
|
* * Added generic unary operators (replace Opposite and Conjugate)Gravatar Gael Guennebaud2008-03-03
| | | | | | | | | | | * functor templates are not template template parameter anymore (this allows to make templated functors !) * Main page: extented compiler discussion * A small hack to support gcc 3.4 and 4.0 (see the main page) * Fix a cast type issue in Cast * Various doxygen updates (mainly Cwise stuff and added doxygen groups in MatrixBase to split the huge memeber list, still not perfect though) * Updated Gael's email address
* Patch by Gael Guennebaud: coeff-wise binary operators.Gravatar Benoit Jacob2008-02-29
| | | | | This unifies + and - and moreover this patch introduces coeff-wise * and / based on this. Also, corresponding test.
* Patch by Gael Guennebaud: unify fixed-size and dynamic-size BlockGravatar Benoit Jacob2008-02-29
| | | | expressions, update documentation.
* Relicense --> dual-license LGPL3+/GPL2+Gravatar Benoit Jacob2008-02-28
|
* prefix global functions with ei_ as previous solution was ratherGravatar Benoit Jacob2008-02-28
| | | | fragile. also fix compilation with g++ 4.3.
* 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
* switch to enums everywhereGravatar Benoit Jacob2008-01-10
|
* 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
* 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.
* - eigen2 now fully enforces constness! found a way to achieve thatGravatar Benoit Jacob2007-12-25
| | | | | | | | with minimal code duplication. There now are only two (2) const_cast remaining in the whole source code. - eigen2 now fully allows copying a row-vector into a column-vector. added a unit-test for that. - split unit tests, improve docs, various improvements.
* rename src/ to Eigen/ so that we're able to #include<Eigen/Core.h>Gravatar Benoit Jacob2007-12-20
| | | | in the examples instead of ugly things like #include"../../src/Core.h"
* split the coeffs accessors/mutators into a separate Coeffs.h fileGravatar Benoit Jacob2007-12-18
|
* add matrix constructor taking an array. update unit-tests.Gravatar Benoit Jacob2007-12-18
|
* add constructors and accessors/mutators specific to small vectors.Gravatar Benoit Jacob2007-12-17
| | | | Add corresponding unit-test.
* -add Ones, DiagonalMatrix, DiagonalCoeffsGravatar Benoit Jacob2007-12-15
| | | | | -expand and improve unit-tests -various renaming and improvements
* expand unit-tests and fix const-qualifaction bugs thus discoveredGravatar Benoit Jacob2007-12-12
