* 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 !
* * 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 resize() methods to Map, doing nothing but assertions.Gravatar Benoit Jacob2008-08-21
| | | | | This is useful in Krita where I call lu().solve() with a Map object as result. As solve() resizes the result, this was needed.
* 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
* 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
* update the inverse test a littleGravatar Benoit Jacob2008-07-26
| | | | | make use of static asserts in Map fix 2 warnings in CacheFriendlyProduct: unused var 'Vectorized'
* * Fix a couple of issues related to the recent cache friendly productsGravatar Gael Guennebaud2008-07-19
| | | | | | | * Improve the efficiency of matrix*vector in unaligned cases * Trivial fixes in the destructors of MatrixStorage * Removed the matrixNorm in test/product.cpp (twice faster and that assumed the matrix product was ok while checking that !!)
* fix a couple of issues in the new Map.hGravatar Benoit Jacob2008-06-27

* * 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.
* 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...
* * add bench/benchVecAdd.cpp by Gael, fix crash (ei_pload on non-aligned)Gravatar Benoit Jacob2008-06-26
| | | | | | | | | | | | * introduce packet(int), make use of it in linear vectorized paths --> completely fixes the slowdown noticed in benchVecAdd. * generalize coeff(int) to linear-access xprs * clarify the access flag bits * rework api dox in Coeffs.h and util/Constants.h * improve certain expressions's flags, allowing more vectorization * fix bug in Block: start(int) and end(int) returned dyn*dyn size * fix bug in Block: just because the Eval type has packet access doesn't imply the block xpr should have it too.
* * 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.
* 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.
* * Draft of a eigenvalues solverGravatar Gael Guennebaud2008-05-12
| | | | | | | | | | | | | | | (does not support complex and does not re-use the QR decomposition) * Rewrite the cache friendly product to have only one instance per scalar type ! This significantly speeds up compilation time and reduces executable size. The current drawback is that some trivial expressions might be evaluated like conjugate or negate. * Renamed "cache optimal" to "cache friendly" * Added the ability to directly access matrix data of some expressions via: - the stride()/_stride() methods - DirectAccessBit flag (replace ReferencableBit)
* * Added ReferencableBit flag to known if coeffRef is available.Gravatar Gael Guennebaud2008-05-08
| | | | | | | | | | | (needed by the new product implementation) * Make the packet* members template to support aligned and unaligned access. This makes Block vectorizable. Combined with ReferencableBit, we should be able to determine at runtime (in some specific cases) if an aligned vectorization is possible or not. * Improved the new product implementation to robustly handle all cases, it now passes all the tests. * Renamed the packet version ei_predux to ei_preduxp to avoid name collision.
* 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.
* 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
* Make use of the LazyBit, introduce .lazy(), remove lazyProduct.Gravatar Benoit Jacob2008-03-31
|
* * 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")
* Patch by Gael Guennebaud:Gravatar Benoit Jacob2008-02-29
| | | | | | | Rework the matrix storage to ensure optimal sizeof in all cases, while keeping the decoupling of matrix sizes versus storage sizes. Also fixing (recently introduced) bugs caused by unwanted reallocations of the buffers.
* Relicense --> dual-license LGPL3+/GPL2+Gravatar Benoit Jacob2008-02-28
|
* 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
* - move: DerivedTraits becomes MatrixBase::TraitsGravatar Benoit Jacob2008-01-06
| | | | | | - the static constants are private again in the Derived classes - more documentation and code snippets - new isDiagonal() method
* remove all the _Order mechanics, now we are always traversing matrices inGravatar Benoit Jacob2008-01-06
| | | | | | | column-major order, even if storage is row-major. Benchmark showed that adapting the traversal order to the storage order brought no benefit. Also do some cleanup after Gael's big patch.
* Patch by Gael Guennebaud, making Eigen compatible with the Intel compiler (icc).Gravatar Benoit Jacob2008-01-06
| | | | CCMAIL:eigen@lists.tuxfamily.org
* - make MatrixBase and all expressions aware of their preferred traversal order.Gravatar Benoit Jacob2008-01-05
| | | | | | | Honor this preference in operator=. - add several methods to the API - rework API for diagonal matrices - add benchmarking code
* more documentation, 12 more code snippetsGravatar Benoit Jacob2008-01-03
|
* cleanup: remove copy contructors when the compiler is able to generate a ↵Gravatar Benoit Jacob2007-12-31
| | | | | | satisfactory default copy constructor; remove useless static_cast's; some misc cleanup.
* move Core/ to a src/ subdir, in preparation for following changesGravatar Benoit Jacob2007-12-28
