* * split Meta.h to Meta.h (generic meta programming) and XprHelper.h (relates ↵Gravatar Gael Guennebaud2008-08-24
| | | | | | | | | to eigen mechanism) * added a meta.cpp unit test * EIGEN_TUNE_FOR_L2_CACHE_SIZE now represents L2 block size in Bytes (whence the ei_meta_sqrt...) * added a CustomizeEigen.dox page * added a TOC to QuickStartGuide.dox
* * add documentation of the cool (?) "print with format" featureGravatar Gael Guennebaud2008-08-23
| | | | | * move the ioformat.cpp test to a documentation example * rename IoFormat => IOFormat
* * 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.
* *patch by Daniel Gomez:Gravatar Gael Guennebaud2008-08-21
| | | | | | - bugfix in SparseMatrix - add a sparse unit test * renamed Transform::affine => linear
* * Add the possibility to customize the output of matrices, e.g.:Gravatar Gael Guennebaud2008-08-21
| | | | | | | | IoFormat OctaveFmt(4, AlignCols, ", ", ";\n", "", "", "[", "]"); cout << mat.format(OctaveFmt); The first "4" is the precision. Documentation missing. * Some compilation fixes
* Add a packetmath unit test, re-enable the comma-initializer unit test,Gravatar Gael Guennebaud2008-08-20
| | | | and bug fix in PacketMath/SSE
* Fix bugs in Sum.h, add unit-testGravatar Benoit Jacob2008-08-20
|
* Added a SVD module:Gravatar Gael Guennebaud2008-08-19
| | | | | | | - the decompostion code has been adfapted from JAMA - handles non square matrices of size MxN with M>=N - does not work for complex matrices - includes a solver where the parts corresponding to zero singular values are set to zero
* Various compilation fixes for MSVC 9. All tests compile but someGravatar Gael Guennebaud2008-08-19
| | | | still fail at runtime in ei_aligned_free() (even without vectorization).
* * 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 LU unit-test. Seems like we have very good numerical stability!Gravatar Benoit Jacob2008-08-09
| | | | * some cleanup, and grant me a copyright line on the determinant test.
* *implement LU solver (solves any rectangular system)Gravatar Benoit Jacob2008-08-09
| | | | | | *in test/CMakeLists : modify EI_ADD_TEST so that 2nd argument is additional compiler flags. used to add -O2 to test_product_large so it doesn't take forever.
* * LU decomposition, supporting all rectangular matrices, with fullGravatar Benoit Jacob2008-08-04
| | | | | | | | | | pivoting for better numerical stability. For now the only application is determinant. * New determinant unit-test. * Disable most of Swap.h for now as it makes LU fail (mysterious). Anyway Swap needs a big overhaul as proposed on IRC. * Remnants of old class Inverse removed. * Some warnings fixed.
* Optimizations:Gravatar Gael Guennebaud2008-08-01
| | | | | | | | * faster matrix-matrix and matrix-vector products (especially for not aligned cases) * faster tridiagonalization (make it using our matrix-vector impl.) Others: * fix Flags of Map * split the test_product to two smaller ones
* * 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.
* * 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
* Started a Transform class in the Geometry module to representGravatar Gael Guennebaud2008-06-15
| | | | | homography. Fix indentation in Quaternion.h
* 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.
* 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
|
* 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
* now the unit-tests (hence all of Eigen) don't depend on Qt at allGravatar Benoit Jacob2008-05-29
| | | | anymore.
* * 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
* 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 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.
* - 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.
* 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
|
* add more unit-tests (covering transpose, conjugate, adjoint, dot product...)Gravatar Benoit Jacob2007-11-28
|
* Fix damage done by automatic search-and-replaceGravatar Benoit Jacob2007-11-25
|
* implement the first _real_ unit-tests, testing the results for correctness ↵Gravatar Benoit Jacob2007-10-13
| | | | | | | | instead of just checking compilation. Fix the many issues discovered by these unit-tests, by the way fixing a performance bug.
* Democracy 1 - 0 DictatorshipGravatar Benoit Jacob2007-10-11
| | | | | | | | | | | | | | | | | | | | | After huge thread on eigen mailing list, it appears that i'm the only one in favor of prefix Ei. Everybody else prefers namespace Eigen like we did in Eigen 1. So, revert. Also add a macro USING_EIGEN_DATA_TYPES that application programmers can use to automatically do "using"on the Matrix class and its matrix/vector typedefs: using Eigen::Matrix; using Eigen::Matrix2d; using Eigen::Vector2d; ... (the list of typedefs is really long). thanks to the suffixes, the Vector typedefs aren't really polluting. CCMAIL:eigen@lists.tuxfamily.org P.S. Danny, please skip this one :) I know you already reported the namespace->prefix move, now that one would be too much noise :)
