* Add a *very efficient* evaluation path for both col-major matrix * vectorGravatar Gael Guennebaud2008-07-12
| | | | | | and vector * row-major products. Currently, it is enabled only is the matrix has DirectAccessBit flag and the product is "large enough". Added the respective unit tests in test/product/cpp.
* - many updates after Cwise changeGravatar Benoit Jacob2008-07-08
| | | | | - fix compilation in product.cpp with std::complex - fix bug in MatrixBase::operator!=
* 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.
* fix issues in previously added additionnal product testsGravatar Gael Guennebaud2008-07-06
|
* * do the ActualPacketAccesBit change as discussed on listGravatar Benoit Jacob2008-07-04
| | | | | * add comment in Product.h about CanVectorizeInner * fix typo in test/product.cpp
* * fix compilation issue in ProductGravatar Gael Guennebaud2008-07-02
| | | | | * added some tests for product and swap * overload .swap() for dynamic-sized matrix of same size
* * added innerSize / outerSize functions to MatrixBaseGravatar Gael Guennebaud2008-06-28
| | | | | | | * added complete implementation of sparse matrix product (with a little glue in Eigen/Core) * added an exhaustive bench of sparse products including GMM++ and MTL4 => Eigen outperforms in all transposed/density configurations !
* * rework Map, allow vectorizationGravatar Benoit Jacob2008-06-27
| | | | | | | | * rework PacketMath and DummyPacketMath, make these actual template specializations instead of just overriding by non-template inline functions * introduce ei_ploadt and ei_pstoret, make use of them in Map and Matrix * remove Matrix::map() methods, use Map constructors instead.
* * 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
* * implement slice vectorization. Because it uses unalignedGravatar Benoit Jacob2008-06-22
| | | | | | | | | packet access, it is not certain that it will bring a performance improvement: benchmarking needed. * improve logic choosing slice vectorization. * fix typo in SSE packet math, causing crash in unaligned case. * fix bug in Product, causing crash in unaligned case. * add TEST_SSE3 CMake option.
* forgot to add the unit test array.cppGravatar Gael Guennebaud2008-06-21

* work on rotations in the Geometry module:Gravatar Gael Guennebaud2008-06-21
| | | | | - convertions are done trough constructors and operator= - added a EulerAngles class
* * added a pseudo expression Array giving access to:Gravatar Gael Guennebaud2008-06-20
| | | | | | | | - matrix-scalar addition/subtraction operators, e.g.: m.array() += 0.5; - matrix/matrix comparison operators, e.g.: if (m1.array() < m2.array()) {} * fix compilation issues with Transform and gcc < 4.1
* * refactoring of Product:Gravatar Gael Guennebaud2008-06-19
| | | | | | | | * use ProductReturnType<>::Type to get the correct Product xpr type * Product is no longer instanciated for xpr types which are evaluated * vectorization of "a.transpose() * b" for the normal product (small and fixed-size matrix) * some cleanning * removed ArrayBase
* Added an extensible mechanism to support any kind of rotationGravatar Gael Guennebaud2008-06-15
| | | | | | representation in Transform via the template static class ToRotationMatrix. Added a lightweight AngleAxis class (similar to Rotation2D).
* * split Product to a DiagonalProduct template specializationGravatar Gael Guennebaud2008-06-15
| | | | | | | | | | to optimize matrix-diag and diag-matrix products without making Product over complicated. * compilation fixes in Tridiagonalization and HessenbergDecomposition in the case of 2x2 matrices. * added an Orientation2D small class with similar interface than Quaternion (used by Transform to handle 2D and 3D orientations seamlessly) * added a couple of features in Transform.
* Started a Transform class in the Geometry module to representGravatar Gael Guennebaud2008-06-15
| | | | | homography. Fix indentation in Quaternion.h
* * Added a generalized eigen solver for the selfadjoint case.Gravatar Gael Guennebaud2008-06-14
| | | | | | (as new members to SelfAdjointEigenSolver) The QR module now depends on Cholesky. * Fix Transpose to correctly preserve the *TriangularBit.
* Add QR and Cholesky module instantiations in the lib.Gravatar Gael Guennebaud2008-06-14
| | | | To try it with the unit tests set the cmake variable TEST_LIB to ON.
* Added a Hessenberg decomposition class for both real and complex matrices.Gravatar Gael Guennebaud2008-06-08
| | | | | | | This is the first step towards a non-selfadjoint eigen solver. Notes: - We might consider merging Tridiagonalization and Hessenberg toghether ? - Or we could factorize some code into a Householder class (could also be shared with QR)
* fix some compile errors with gcc 4.3, some warnings, some documentationGravatar Benoit Jacob2008-06-06
|
* hack to to make the nomalloc unit test compiles with -pedanticGravatar Gael Guennebaud2008-06-04
|
* update of the eigeinsolver unit test to check complexGravatar Gael Guennebaud2008-06-03
|
* * add CommaInitializer::finished to allow the use of (Matrix3() << v0, v1, ↵Gravatar Gael Guennebaud2008-06-03
| | | | | | | | v2).finished() as an argument of a function. Other possibilities for the name could be "end" or "matrix" ?? * various update in Quaternion, in particular I added a lot of FIXME about the API options, these have to be discussed and fixed.
* improved Quaternion class:Gravatar Gael Guennebaud2008-06-03
| | | | | | | - Euler angles and angle axis conversions, - stable spherical interpolation - documentation - update the respective unit test
* 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
|
* fix a couple of issues making the eigensolver test compile and run without ↵Gravatar Benoit Jacob2008-06-02
| | | | | | | | | aborting on an assert. Had to fix a stupid bug in Block -- very strange we hadn't hit it before. However the test still fails.
* added a unit test for InverseGravatar Gael Guennebaud2008-05-31
| | | | | discovered that m1 == m1.inverse().inverse() fails though m1.inverse()*m1 == I
* added an *optional* Eigen2 dynamic library.Gravatar Gael Guennebaud2008-05-31
| | | | | it allows the possiblity to save some compilation time by linking to it *and* defining the token EIGEN_EXTERN_INSTANCIATIONS
* 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.
* many small fixes and documentation improvements,Gravatar Benoit Jacob2008-05-29
| | | | this should be alpha5.
* * find the proper way of nesting the expression in Flagged:Gravatar Benoit Jacob2008-05-28
| | | | | | | | | | | | | finally that's more subtle than just using ei_nested, because when flagging with NestByValueBit we want to store the expression by value already, regardless of whether it already had the NestByValueBit set. * rename temporary() ----> nestByValue() * move the old Product.h to disabled/, replace by what was ProductWIP.h * tweak -O and -g flags for tests and examples * reorder the tests -- basic things go first * simplifications, e.g. in many methoeds return derived() and count on implicit casting to the actual return type. * strip some not-really-useful stuff from the heaviest tests
* * 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
|
* * 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
|
* - 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
