* * add PermutationMatrixGravatar Benoit Jacob2009-11-15
| | | | | | | * DiagonalMatrix: - add MaxSizeAtCompileTime parameter - DiagonalOnTheLeft ---> OnTheLeft - fix bug in DiagonalMatrix::setIdentity()
* finish my evalToDense => evalTo changeGravatar Gael Guennebaud2009-09-17
|
* remove the \addexample tagsGravatar Gael Guennebaud2009-09-03
|
* * Bye bye MultiplierBase, extend a bit AnyMatrixBase to allow =, +=, and -=Gravatar Gael Guennebaud2009-08-03
| | | | * This probably makes ReturnByValue needless
* add a generic mechanism to copy a special matrix to a dense matrix so thatGravatar Gael Guennebaud2009-07-07
| | | | | we don't need to add other specialization of MatrixBase::operator=, Matrix::=, and Matrix::Matrix(...)
* * update sparse module wrt new diagonal matrix implGravatar Gael Guennebaud2009-07-04
| | | | * fix a bug is SparseMatrix
* new implementation of diagonal matrices and diagonal matrix expressionsGravatar Benoit Jacob2009-06-28
|
* remove sentence "Eigen itself is part of the KDE project."Gravatar Benoit Jacob2009-05-22
| | | | it never made very precise sense. but now does it still make any?
* constant Diagonal ---> DiagonalBitsGravatar Benoit Jacob2009-05-10
| | | | | | introduce ei_is_diagonal to check for it DiagonalCoeffs ---> Diagonal and allow Index to by Dynamic -> add MatrixBase::diagonal(int) with unittest and doc
* ok, this time cast should really work ; sorry for the noiseGravatar Gael Guennebaud2009-04-29
|
* add DiagonalMatrix setZero and resize functionsGravatar Gael Guennebaud2009-02-09
|
* fix MSVC stupid warningsGravatar Gael Guennebaud2009-01-29
|
* add MatrixBase::stableNorm() avoiding over/under-flowGravatar Gael Guennebaud2009-01-28
| | | | | using it in QR reduced the error of Keir test from 1e-12 to 1e-24 but that's much more expensive !
* * make sum and redux honor EvalBeforeNestingBit tooGravatar Gael Guennebaud2009-01-28
| | | | * fix MSVC issues (hopefully)
* 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
* * replace postfix ++ by prefix ++ wherever that makes sense in Eigen/Gravatar Benoit Jacob2008-12-17
| | | | | * fix some "unused variable" warnings in the tests; there remains a libstdc++ "deprecated" warning which I haven't looked much into
* bugfix in DiagonalProduct: a "DiagonalProduct<SomeXpr>" expressionGravatar Gael Guennebaud2008-12-10
| | | | | is now evaluated as a "DiagonalProduct<Matrix<SomeXpr::Eval> >". Note that currently this only happens in DiagonalProduct.
* Update e-mail addressGravatar Benoit Jacob2008-11-24
|
* * Add Hyperplane::transform(Matrix/Transform)Gravatar Gael Guennebaud2008-08-31
| | | | | * Fix compilations with gcc 3.4, ICC and doxygen * Fix krazy directives (hopefully)
* doc and use sed to clean the class hierarchy instead ofGravatar Gael Guennebaud2008-08-28
| | | | preprocessor directives.
* * move memory related stuff to util/Memory.hGravatar Gael Guennebaud2008-08-26
| | | | | * clean ugly doxygen inheritence of expressions * keep improving the documentation... slowly !
* Added an automatically generated list of selected examples in the documentation.Gravatar Gael Guennebaud2008-07-19
| | | | Added the custom gemetry_module tag, and use it.
* change derived classes methods from "private:_method()"Gravatar Benoit Jacob2008-06-26
| | | | | | | | to "public:method()" i.e. reimplementing the generic method() from MatrixBase. improves compilation speed by 7%, reduces almost by half the call depth of trivial functions, making gcc errors and application backtraces nicer...
* meagre outcome for so much time spent!Gravatar Benoit Jacob2008-06-01
| | | | | | * fix inverse() bug discovered by Gael's test * fix warnings introduced by the new Diagonal stuff * update Doxyfile to v1.5.6
* added optimized matrix times diagonal matrix product via Diagonal flag shortcut.Gravatar Gael Guennebaud2008-05-31
|
* * 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
* Introduce generic Flagged xpr, remove already Lazy.h and Temporary.hGravatar Benoit Jacob2008-05-14
| | | | Rename DefaultLostFlagMask --> HerediraryBits
* put inline keywords everywhere appropriate. So we don't need anymore to passGravatar Benoit Jacob2008-05-12
| | | | -finline-limit=1000 to gcc to get good performance. By the way some cleanup.
* fix flag and cost computations for nested expressionsGravatar Gael Guennebaud2008-05-01
|
* Added Triangular expression to extract upper or lower (strictly or not)Gravatar Gael Guennebaud2008-04-26
| | | | | | | | | | | part of a matrix. Triangular also provide an optimised method for forward and backward substitution. Further optimizations regarding assignments and products might come later. Updated determinant() to take into account triangular matrices. Started the QR module with a QR decompostion algorithm. Help needed to build a QR algorithm (eigen solver) based on it.
* Fix a couple of issue with the vectorization. In particular, default ei_p* ↵Gravatar Gael Guennebaud2008-04-24
| | | | | | | | | functions are provided to handle not suported types seemlessly. Added a generic null-ary expression with null-ary functors. They replace Zero, Ones, Identity and Random.
* * rename XprCopy -> NestedGravatar Benoit Jacob2008-04-10
| | | | | * rename OperatorEquals -> Assign * move Util.h and FwDecl.h to a util/ subdir
* 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.
* -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
* * introducte recursive Flags system for the expressionsGravatar Benoit Jacob2008-03-30
| | | | | | -- currently 3 flags: RowMajor, Lazy and Large -- only RowMajor actually used for now * many minor improvements
* * #define EIGEN_NDEBUG now also disables asserts. UsefulGravatar Benoit Jacob2008-03-26
| | | | | | | | | | | | to disable eigen's asserts without disabling one's own program's asserts. Notice that Eigen code should now use ei_assert() instead of assert(). * Remove findBiggestCoeff() as it's now almost redundant. * Improve echelon.cpp: inner for loop replaced by xprs. * remove useless "(*this)." here and there. I think they were first introduced by automatic search&replace. * fix compilation in Visitor.h (issue triggered by echelon.cpp) * improve comment on swap().
* get rid of MatrixRef, simplifications.Gravatar Benoit Jacob2008-03-13
|
* a lot of renamingGravatar Benoit Jacob2008-03-13
| | | | | | | | internal classes: AaBb -> ei_aa_bb IntAtRunTimeIfDynamic -> ei_int_if_dynamic unify UNROLLING_LIMIT (there was no reason to have operator= use a higher limit) etc...
* 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.
* renaming: ref() --> asArg()Gravatar Benoit Jacob2008-03-04
|
* * Eigen compiles with any GCC versions from, at least, 3.3 without the ↵Gravatar Gael Guennebaud2008-03-04
| | | | | | previous ugly hack :) * Renamed the scalar functors with the "Scalar" prefix (instead of "Cwise")
* 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.
* alpha 3.1. in this commit:Gravatar Benoit Jacob2008-01-15
| | | | | | | | | - finally get the Eval stuff right. get back to having Eval as a subclass of Matrix with limited functionality, and then, add a typedef MatrixType to get the actual matrix type. - add swap(), findBiggestCoeff() - bugfix by Ramon in Transpose - new demo: doc/echelon.cpp
* big architecture change dissociating "actual" dimensions from "maximum possible"Gravatar Benoit Jacob2008-01-13
| | | | | | | dimension. The advantage is that evaluating a dynamic-sized block in a fixed-size matrix no longer causes a dynamic memory allocation. Other new thing: IntAtRunTimeIfDynamic allows storing an integer at zero cost if it is known at compile time.
* -add set...() methods and their documentation; remove GenericGravatar Benoit Jacob2008-01-11
| | | | | | -use row-major traversal when the number of columns is fixed and the number of rows is dynamic -other minor changes
* switch to enums everywhereGravatar Benoit Jacob2008-01-10
|
* Ready for alpha2 release.Gravatar Benoit Jacob2008-01-07
| | | | | | - complete documentation - add TODO - update copyright years
