* big addons:Gravatar Gael Guennebaud2009-03-05
| | | | | | | | | | | * add Homogeneous expression for vector and set of vectors (aka matrix) => the next step will be to overload operator* * add homogeneous normalization (again for vector and set of vectors) * add a Replicate expression (with uni-directional replication facilities) => for all of them I'll add examples once we agree on the API * fix gcc-4.4 warnings * rename reverse.cpp array_reverse.cpp
* add ReturnByValue pseudo expression for in-place evaluation with aGravatar Gael Guennebaud2009-03-04
| | | | return-by-value API style (will soon use it for the transform products)
* apply Ricard patch for Reverse with minor modificationsGravatar Gael Guennebaud2009-02-06
|
* Add sub/super-diagonal expression (read/write) as a trivial extension ofGravatar Gael Guennebaud2009-02-05
| | | | | | | DiagonalCoeffs. The current API is simply: m.diagonal<1>() => 1st super diagonal m.diagonal<-2>() => the 2nd sub diagonal I'll add a code snippet once we agree on this API.
* Big change in DiagonalMatrix and Geometry/Scaling:Gravatar Gael Guennebaud2009-01-28
| | | | | | | | | | | | | | | * previous DiagonalMatrix expression is now DiagonalMatrixWrapper * DiagonalMatrix class is now for storage * add the DiagonalMatrixBase class to factorize code of the two previous classes * remove Scaling class (it is now a global function) * add UniformScaling helper class (don't use it directly, use the Scaling function) * add the Scaling global function to simplify the creation of scaling objects There is still a lot to do, in particular about DiagonalProduct for which the goal is to get rid of the "if()" in the coeff() function. At least it is not worse than before ! Also need to uptade the tutorial and add more doc.
* * clarify the situation with experimental partsGravatar Benoit Jacob2009-01-19
| | | | * remove all what was marked deprecated
* Add support for sparse * dense and dense * sparse matrix/vector productsGravatar Gael Guennebaud2009-01-14
|
* remove the Matrix_ prefixGravatar Benoit Jacob2009-01-06
|
* * the 4th template param of Matrix is now Options. One bit for storageGravatar Benoit Jacob2009-01-04
| | | | | | | | | | | | | | | | order, one bit for enabling/disabling auto-alignment. If you want to disable, do: Matrix<float,4,1,Matrix_DontAlign> The Matrix_ prefix is the only way I can see to avoid ambiguity/pollution. The old RowMajor, ColMajor constants are deprecated, remain for now. * this prompted several improvements in matrix_storage. ei_aligned_array renamed to ei_matrix_array and moved there. The %16==0 tests are now much more centralized in 1 place there. * unalignedassert test: updated * update FindEigen2.cmake from KDElibs * determinant test: use VERIFY_IS_APPROX to fix false positives; add testing of 1 big matrix
* Update e-mail addressGravatar Benoit Jacob2008-11-24
|
* * add .imag() functionGravatar Gael Guennebaud2008-11-14
| | | | | | * fix a very old bug in EigenSolver that I had completely forgotten (thanks to Timothy to refresh my mind) * fix doc of Matrix::Map
* Big API change in Cholesky module:Gravatar Gael Guennebaud2008-10-13
| | | | | | | | | | | | | | | | * rename Cholesky to LLT * rename CholeskyWithoutSquareRoot to LDLT * rename MatrixBase::cholesky() to llt() * rename MatrixBase::choleskyNoSqrt() to ldlt() * make {LLT,LDLT}::solve() API consistent with other modules Note that we are going to keep a source compatibility untill the next beta release. E.g., the "old" Cholesky* classes, etc are still available for some time. To be clear, Eigen beta2 should be (hopefully) source compatible with beta1, and so beta2 will contain all the deprecated API of beta1. Those features marked as deprecated will be removed in beta3 (or in the final 2.0 if there is no beta 3 !). Also includes various updated in sparse Cholesky.
* move CommaInitializer out of MatrixBase and documment it (because of ↵Gravatar Gael Guennebaud2008-09-13
| | | | .finished())
* Add a Select expression in the Array module which mimics a coeff-wise ?: ↵Gravatar Gael Guennebaud2008-09-03
| | | | | | | | operator. Example: mat = (mat.cwise().abs().cwise() < Ones()).select(0,mat); replaces all small values by 0. (the scalar version is "s = abs(s)<1 ? 0 : s")
* Extended sparse unit-test: nested blocks and InnerIterators.Gravatar Daniel Gomez Ferro2008-09-02
| | | | | Block specialization for sparse matrices. InnerIterators for Blocks and fixes in CoreIterators.
* The discussed changes to Hyperplane, the ParametrizedLine class, and theGravatar Benoit Jacob2008-08-31
| | | | API update in Regression...
* Split Rotation.h to Rotation2D.h and RotationBase.h,Gravatar Gael Guennebaud2008-08-30
| | | | | and more code factorization based on RotationBase. Added notes about the main aim of the Translation and Scaling classes.
* Add Scaling and Translation class as discussed on ML, still missing:Gravatar Gael Guennebaud2008-08-30
| | | | | | | | * handling Quaternion, AngleAxis and Rotation2D, 2 options here: 1- make all of them inheriting a common base class Rotation such that we can have a single version of operator* for all the rotation type (they all get converted to a matrix) 2- write a version for all type (so 3 rotations types * 3 for Transform,Translation and Scaling) * real documentation
* doc + quick bug fix in Matrix ctorGravatar Gael Guennebaud2008-08-28
|
* * 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
* * remove LargeBit and related stuffGravatar Gael Guennebaud2008-08-23
| | | | | | | * replaced the Flags template parameter of Matrix by StorageOrder and move it back to the 4th position such that we don't have to worry about the two Max* template parameters * extended EIGEN_USING_MATRIX_TYPEDEFS with the ei_* math functions
* * 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
* 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
* Renamed allowAligned() => forceAligned() and added the constants ForceAlignedGravatar Gael Guennebaud2008-08-09
| | | | | and AsRequested for the PacketAccess parameter of MapBase. Updated respective documentation.
* * Big change in Block and Map:Gravatar Gael Guennebaud2008-08-09
| | | | | | | | | | | | | | - 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
* New implementation of Swap as discussed, reusing Assign. Makes LU runGravatar Benoit Jacob2008-08-05
| | | | 10% faster overall.
* * 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.
* removed the packet specializations of some functorsGravatar Gael Guennebaud2008-07-31
| | | | (GCC generates better code without those "optimizations")
* Add cholesky's members to MatrixBaseGravatar Gael Guennebaud2008-07-19
| | | | Various documentation improvements including new snippets (AngleAxis and Cholesky)
* Added MatrixBase::Unit*() static function to easily create unit/basis vectors.Gravatar Gael Guennebaud2008-07-19
| | | | | | | Removed EulerAngles, addes typdefs for Quaternion and AngleAxis, and added automatic conversions from Quaternion/AngleAxis to Matrix3 such that: Matrix3f m = AngleAxisf(0.2,Vector3f::UnitX) * AngleAxisf(0.2,Vector3f::UnitY); just works.
* Complete rewrite of partial reduction according to mailing list discussions.Gravatar Gael Guennebaud2008-07-19
|
* * Optimization: added a specialization of Block for xpr with DirectAccessBitGravatar Gael Guennebaud2008-07-12
| | | | * some simplifications and fixes in cache friendly products
* 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.
* * 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.
* 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
* * Block: row and column expressions in the inner directionGravatar Benoit Jacob2008-06-16
| | | | | | | | | now have the Like1D flag. * Big renaming: packetCoeff ---> packet VectorizableBit ---> PacketAccessBit Like1DArrayBit ---> LinearAccessBit
* * Big rework of Assign.h:Gravatar Benoit Jacob2008-06-16
| | | | | | | | | | | | | | | ** Much better organization ** Fix a few bugs ** Add the ability to unroll only the inner loop ** Add an unrolled path to the Like1D vectorization. Not well tested. ** Add placeholder for sliced vectorization. Unimplemented. * Rework of corrected_flags: ** improve rules determining vectorizability ** for vectors, the storage-order is indifferent, so we tweak it to allow vectorization of row-vectors. * fix compilation in benchmark, and a warning in Transpose.
* 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).
* 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.
* * make the _Flags template parameter of Matrix default to the correctedGravatar Benoit Jacob2008-06-13
| | | | | | | | | flags. This ensures that unless explicitly messed up otherwise, a Matrix type is equal to its own Eval type. This seriously reduces the number of types instantiated. Measured +13% compile speed, -7% binary size. * Improve doc of Matrix template parameters.
* add a geometry unit test and fix a couple of typo in Quaternion.hGravatar Gael Guennebaud2008-06-03
|
* * added a Tridiagonalization class for selfadjoint matricesGravatar Gael Guennebaud2008-06-01
| | | | | | | | | * added MatrixBase::real() * added the ability to extract a selfadjoint matrix from the lower or upper part of a matrix, e.g.: m.extract<Upper|SelfAdjoint>() will ignore the strict lower part and return a selfadjoint. This is compatible with ZeroDiag and UnitDiag.
* 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
* added optimized matrix times diagonal matrix product via Diagonal flag shortcut.Gravatar Gael Guennebaud2008-05-31
|
* 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
* Added ArrayBit to get the ability to manipulate a Matrix like a simple scalar.Gravatar Gael Guennebaud2008-05-29
| | | | In particular this flag changes the behavior of operator* to a coeff wise product.
* hehe, the complicated nesting scheme in Flagged in the previous commitGravatar Benoit Jacob2008-05-28
| | | | | | | | | | | was a sign that we were doing something wrong. In fact, having NestByValue as a special case of Flagged was wrong, and the previous commit, while not buggy, was inefficient because then when the resulting NestByValue xpr was nested -- hence copied -- the original xpr which was already nested by value was copied again; hence instead of 1 copy we got 3 copies. The solution was to ressuscitate the old Temporary.h (renamed NestByValue.h) as it was the right approach.
* - 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
