* * introduced method createRandomMatrixOfRank (R = U*D*V where U,V unitary, D ↵Gravatar Hauke Heibel2009-05-17
| | | | | | | | r-by-c diag. with rank non-zero values) * switched lu/qr tests to be using createRandomMatrixOfRank * removed unused methods doSomeRankPreservingOperations * removed NOTE about doSomeRankPreservingOperations
* Add full pivoting to LDLT decomposition.Gravatar Keir Mierle2009-02-03

* * 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.
* improved MSVC support in cmake files (SSE)Gravatar Gael Guennebaud2008-12-18

* some cmake fixes for windows and GSLGravatar Gael Guennebaud2008-12-17
|
* * throw bad_alloc if exceptions are enabled, after patch by Kenneth RiddileGravatar Benoit Jacob2008-12-16
| | | | * disable vectorization on MSVC 2005, as it doesn't have all the required intrinsics. require 2008.
* * 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
* Update e-mail addressGravatar Benoit Jacob2008-11-24
|
* Add isApprox in Geometry module's classes.Gravatar Gael Guennebaud2008-10-25
| | | | Complete unit tests wrt previous commits.

* * Extend a bit ParametrizedLine and move it to a separate file,Gravatar Gael Guennebaud2008-09-03
| | | | | | add unit-tests for it. * remove "using namespace std" in test/main.h such that the compilation bug found today in SVD won't happen again.
* 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.
* * Add Hyperplane::transform(Matrix/Transform)Gravatar Gael Guennebaud2008-08-31
| | | | | * Fix compilations with gcc 3.4, ICC and doxygen * Fix krazy directives (hopefully)
* * 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...
* * add Regression module, from eigen1, improved, with doc and unit-test.Gravatar Benoit Jacob2008-08-11
| | | | | | | | | * fix .normalized() so that Random().normalized() works; since the return type became complicated to write down i just let it return an actual vector, perhaps not optimal. * add Sparse/CMakeLists.txt. I suppose that it was intentional that it didn't have CMakeLists, but in <=2.0 releases I'll just manually remove Sparse.
* add a geometry unit test and fix a couple of typo in Quaternion.hGravatar Gael Guennebaud2008-06-03
|
* added unit tests for sizeof and dynamic memory allocationGravatar Gael Guennebaud2008-06-02
|
* moved purely "array" related stuff to a new module Array.Gravatar Gael Guennebaud2008-05-31
| | | | | | | | This include: - cwise Pow,Sin,Cos,Exp... - cwise Greater and other comparison operators - .any(), .all() and partial reduction - random
* now the unit-tests (hence all of Eigen) don't depend on Qt at allGravatar Benoit Jacob2008-05-29
| | | | anymore.
* 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.
* * Patch by Konstantinos Margaritis: AltiVec vectorization.Gravatar Benoit Jacob2008-05-03
| | | | * Fix several warnings, temporarily disable determinant test.
* * added ei_sqrt for complexGravatar Gael Guennebaud2008-04-27
| | | | | * 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
|
* 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 LazyBit, introduce .lazy(), remove lazyProduct.Gravatar Benoit Jacob2008-03-31
|
* * 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
|
* 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.
* * 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: 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.
* 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.
* Ready for alpha2 release.Gravatar Benoit Jacob2008-01-07
| | | | | | - complete documentation - add TODO - update copyright years
* - 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"
* 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 and improve unit-testsGravatar Benoit Jacob2007-12-11
|
* big reorganisation of asserts, so that:Gravatar Benoit Jacob2007-12-05
| | | | | | | | 0) asserts are only done in the public API, except for a few ones explicitly named eigen_internal_assert. 1) internal asserts are disabled unless EIGEN_INTERNAL_DEBUGGING is defined. This limits the impact of debugging on performance. 2) no 'unused argument' warnings anymore when compiling with -DNDEBUG
* rename Block to DynBlock and rework API to make place forGravatar Benoit Jacob2007-12-05
| | | | upcoming fixed-size Block matrix. Also some cleanup.
