  • da674fa032 Shut up two bogus gcc 4.3 warnings Benoit Jacob 2008-08-25 03:13:14 +00:00
  • 5ac883b10a Fix a bug discovered in Avogadro: the AngleAxis*Matrix and the newer AngleAxis*Vector products were wrong because they returned the product _expression_ toRotationMatrix()*other; and toRotationMatrix() died before that expression would be later evaluated. Here it would not have been practical to NestByValue as this is a whole matrix. So, let them simply evaluate and return the result by value. Benoit Jacob 2008-08-24 23:16:51 +00:00
  • aa54d6bef0 arf, of course a meta-selector was required here Benoit Jacob 2008-08-24 21:36:14 +00:00

  • bf31d81aac argh, gael you're more clever than i remembered. diagonal product is optimized. so, i almost revert, just reordering to reduce # of load/store. Benoit Jacob 2008-08-24 20:53:04 +00:00
  • d3529e9c40 optimization: spare the 3x3 matrix product in fromPositionOrientationScale Benoit Jacob 2008-08-24 20:50:18 +00:00
  • 6a36b5a6e0 add AngleAxis::operator*(const Vector3&) Benoit Jacob 2008-08-24 20:13:32 +00:00

  • 440664cd5d temporary fix of the pèrevious commit Gael Guennebaud 2008-08-24 15:27:05 +00:00
  • ba100998bf * split Meta.h to Meta.h (generic meta programming) and XprHelper.h (relates 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 Gael Guennebaud 2008-08-24 15:15:32 +00:00
  • bfe86b8fc0 * add documentation of the cool (?) "print with format" feature * move the ioformat.cpp test to a documentation example * rename IoFormat => IOFormat Gael Guennebaud 2008-08-23 19:41:00 +00:00

  • 8509668466 bugfix from Timothy Hunter s/ei_div/ei_pdiv Gael Guennebaud 2008-08-22 22:01:02 +00:00
  • e0f627a7db s/Affine/Linear, thanks to Thomas Vaughan Gael Guennebaud 2008-08-22 17:54:37 +00:00
  • f0394edfa7 * bugfix in SolveTriangular found by Timothy Hunter (did not compiled for 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... Gael Guennebaud 2008-08-22 17:48:36 +00:00
  • a95c1e190b patch from Konstantinos Margaritis: Altivec vectorization is resurrected ! Gael Guennebaud 2008-08-22 13:19:35 +00:00
  • 95db4e9841 added SparseSetter doc Gael Guennebaud 2008-08-22 11:19:12 +00:00
  • a814ebe180 fix a number of compiler errors and warnings with gcc 4.3. There was a missing #include<algorithm> so I'm not sure how it compiled at all for you :) Benoit Jacob 2008-08-22 01:19:53 +00:00
  • db628c6ad7 Reimplement fitHyperplane such that the fit is done in a total LS sense (use eigen decomposition). Added optional feedback on the stability of the actual fit (think about fitting a 3D plane on data lying on a line...) Gael Guennebaud 2008-08-22 00:09:46 +00:00
  • 0998c51d1f - remove the ASM macro as in fact Gael had been removing all the remaining asm("...") from the code while fixing MSVC compat (so your changes crossed one another). - move the pragma warning to CoreDeclarations, it's the right place to do early platform checks. Benoit Jacob 2008-08-21 21:07:24 +00:00
  • 58061f5ffc extend sparse unit test and more bugfix, major todo: finilize the SparseSetter Gael Guennebaud 2008-08-21 18:40:56 +00:00
  • 60804c306d *patch by Daniel Gomez: - bugfix in SparseMatrix - add a sparse unit test * renamed Transform::affine => linear Gael Guennebaud 2008-08-21 17:02:47 +00:00
  • 082e309d2a patch by Patrick Spendrin: fix MSVC compatibility Benoit Jacob 2008-08-21 16:17:51 +00:00
  • 67813e01bf disable the vectorization of div for AltiVec Gael Guennebaud 2008-08-21 14:03:17 +00:00
  • f729fc1d70 * Add the possibility to customize the output of matrices, e.g.: IoFormat OctaveFmt(4, AlignCols, ", ", ";\n", "", "", "[", "]"); cout << mat.format(OctaveFmt); The first "4" is the precision. Documentation missing. * Some compilation fixes Gael Guennebaud 2008-08-21 13:17:21 +00:00
  • 591d497b84 add resize() methods to Map, doing nothing but assertions. This is useful in Krita where I call lu().solve() with a Map object as result. As solve() resizes the result, this was needed. Benoit Jacob 2008-08-21 04:36:48 +00:00
  • 84a39e04bf added Sub matrices section and a couple of cross ref to the API doc Gael Guennebaud 2008-08-20 23:04:58 +00:00
  • fd681507dc Add a packetmath unit test, re-enable the comma-initializer unit test, and bug fix in PacketMath/SSE Gael Guennebaud 2008-08-20 20:08:38 +00:00
  • ff8e98c974 Fix bugs in Sum.h, add unit-test Benoit Jacob 2008-08-20 16:43:28 +00:00
  • c501c7a4ef * Fix CMakeLists.txt issue with SVD * Fix on stack memory allocation issues Gael Guennebaud 2008-08-20 15:58:01 +00:00

  • 8afaeb4ad5 doc fixes, and extended Basic Linear Algebra and Reductions sections Gael Guennebaud 2008-08-20 13:07:46 +00:00
  • db8fbf2b39 some updated of the quick start guide Gael Guennebaud 2008-08-20 11:31:50 +00:00
  • c705c38a23 * it's \returns not \Returns * add some explanations in the typedefs page * expand a bit the new QuickStartGuide. Some placeholders (not a pb since it's not even yet linked to from other pages). The point I want to make is that it's super important to have fully compilable short programs (even with compile instructions for the first one) not just small snippets, at least at the beginning. Let's start with examples of compilable programs. Benoit Jacob 2008-08-20 04:34:04 +00:00
  • 8551fe28ce fix a few typos Gael Guennebaud 2008-08-20 01:12:56 +00:00
  • 7aba51ce53 * Added .all() and .any() members to PartialRedux * Bug fixes in euler angle snippet, Assign and MapBase * Started a "quick start guide" (draft state) Gael Guennebaud 2008-08-20 00:58:25 +00:00
  • c6674ab076 missing SVD header file Gael Guennebaud 2008-08-19 20:18:46 +00:00
  • 104f8fd36e Added a SVD module: - 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 Gael Guennebaud 2008-08-19 17:52:04 +00:00
  • 54137f1ca7 * fix bug found by Boudewijn Rempt: no CMakeLists in arch/ subdir * fix warning in SolveTriangular Benoit Jacob 2008-08-19 13:15:13 +00:00
  • a6d387a359 Various compilation fixes for MSVC 9. All tests compile but some still fail at runtime in ei_aligned_free() (even without vectorization). Gael Guennebaud 2008-08-19 11:06:40 +00:00
  • 9466e5f94e * doc improvements in Cwise and PartialRedux: - 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. Benoit Jacob 2008-08-19 04:30:28 +00:00
  • 95dd09bea6 * revert the previous interface change in solveTriangular (pointer vs reference) * remove the cast operators in the Geometry module: they are replaced by constructors and new operator= in Matrix * extended the operations supported by Rotation2D * rewrite in solveTriangular: - merge the Upper and Lower specializations - big optimization of the path for row-major triangular matrices Gael Guennebaud 2008-08-18 22:17:42 +00:00
  • e778ae2559 only use alloca on linux. Use malloc on other platforms. Needed for mingw compatibility. Benoit Jacob 2008-08-18 16:36:47 +00:00
  • baf0cffedd *add operator()(int) for vectors, synonymous to operator[](int). I don't see any reason not to allow it, it doesn't add much code, and it makes porting from eigen1 easier. *expand tests/basicstuff to first test coefficient access methods Benoit Jacob 2008-08-18 12:33:14 +00:00
  • 95a1283bf6 fix compilation of unit-tests when cmake is run on kdesupport/ parent directory Benoit Jacob 2008-08-17 15:25:53 +00:00
  • 239b47e033 *make Eigen2 install to prefix/include/eigen2/Eigen *Add FindEigen2.cmake module in kdelibs Benoit Jacob 2008-08-16 12:56:38 +00:00
  • 5546e963c9 bugfix in CholeskyWithoutSquareRoot::solve found by Timothy Hunter Gael Guennebaud 2008-08-16 07:09:39 +00:00
  • d9d69de382 updated tutorial Benoit Jacob 2008-08-15 14:28:06 +00:00
  • 3bc2746928 Copy eigen2 into kdesupport, alongside eigen1 for now, co-installable, will remove eigen1 once no code uses it anymore (soon). Benoit Jacob 2008-08-14 13:21:11 +00:00
  • 8a3e6b1ee2 change solveTriangularInPlace() to take a pointer as input (as discussed on IRC). extended the documentation of the triangular solver. Gael Guennebaud 2008-08-12 07:49:59 +00:00
  • 13ad88736e last small fixes, this is alpha6, eigen2 is now ready for eigen1 apps to port to. Benoit Jacob 2008-08-12 02:14:02 +00:00
  • f04c1cb774 Complete LU documentation Benoit Jacob 2008-08-11 21:26:37 +00:00
  • 17ec407ccd * add Regression module, from eigen1, improved, with doc and unit-test. * 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. Benoit Jacob 2008-08-11 02:25:40 +00:00
  • 55e8d670ce Renamed allowAligned() => forceAligned() and added the constants ForceAligned and AsRequested for the PacketAccess parameter of MapBase. Updated respective documentation. Gael Guennebaud 2008-08-09 21:57:50 +00:00
  • b13148c358 renamed inverseProduct => solveTriangular Gael Guennebaud 2008-08-09 20:06:25 +00:00
  • d6e88f8155 * add LU unit-test. Seems like we have very good numerical stability! * some cleanup, and grant me a copyright line on the determinant test. Benoit Jacob 2008-08-09 19:26:14 +00:00
  • 4fa40367e9 * Big change in Block and Map: - added a MapBase base xpr on top of which Map and the specialization of Block are implemented - MapBase forces both aligned loads (and aligned stores, see below) in expressions such as "x.block(...) += other_expr" * Significant vectorization improvement: - added a AlignedBit flag meaning the first coeff/packet is aligned, this allows to not generate extra code to deal with the first unaligned part - removed all unaligned stores when no unrolling - removed unaligned loads in Sum when the input as the DirectAccessBit flag * Some code simplification in CacheFriendly product * Some minor documentation improvements Gael Guennebaud 2008-08-09 18:41:24 +00:00
  • becbeda50a * reimplement the general case of inverse() on top of LU. Advantages: - removes much code - 2.5x faster (even though LU uses complete pivoting contrary to what inverse used to do!) - there _were_ numeric stability problems with the partial pivoting approach of inverse(), with 200x200 matrices inversion failed almost half of the times (overflow). Now these problems are solved thanks to complete pivoting. Benoit Jacob 2008-08-09 15:50:07 +00:00
  • 681e944670 *implement LU solver (solves any rectangular system) *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. Benoit Jacob 2008-08-09 15:23:54 +00:00
  • a41f2b4216 * fix bug in SwapWrapper : store the wrapped expression by reference * optimize setIdentity: when the matrix is large enough it is better to setZero() and overwrite the diagonal * start of LU solver, disabled for now Benoit Jacob 2008-08-09 04:37:09 +00:00
  • 9bbe396939 forgot to remove that old code Benoit Jacob 2008-08-07 21:50:29 +00:00
  • 5f350448e1 - add kernel computation using the triangular solver - take advantage of the fact that our LU dec sorts the eigenvalues of U in decreasing order - add meta selector in determinant Benoit Jacob 2008-08-07 21:48:21 +00:00
  • 58ba9ca72f LU: remove partial-pivoting path (moderately useful since it's does not allow to easily get the rank), fix a bug (which could have been triggered by matrices having coefficients of very different magnitudes). Part: add an assert to prevent hard to find bugs Swap: update comments Benoit Jacob 2008-08-07 04:31:05 +00:00
