* Add the following functions:Gravatar David Tellenbach2021-01-28
| | | | | | | | | | | DenseBase::setZero(NoChange_t, Index) DenseBase::setZero(Index, NoChange_t) DenseBase::setOnes(NoChange_t, Index) DenseBase::setOnes(Index, NoChange_t) DenseBase::setRandom(NoChange_t, Index) DenseBase::setRandom(Index, NoChange_t) This closes #663.

* bug #1286: automatically detect the available prototypes of functors passed ↵Gravatar Gael Guennebaud2016-08-31
| | | | | | | | | to CwiseNullaryExpr such that functors have only to implement the operators that matters among: operator()() operator()(i) operator()(i,j) Linear access is also automatically detected based on the availability of operator()(i,j).
* Fix return nullary return types: it must be based on the PlainObject type ↵Gravatar Gael Guennebaud2015-06-22

* finish to merge Array into Core:Gravatar Gael Guennebaud2010-06-19
| | | | | - mv Array/* into Core/ - merge Functors.h files, and move Norms.h into Dot.h
* 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.
* 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.
* current state of the mess. One line fails in the tests, andGravatar Benoit Jacob2008-04-03
| | | | | | | | | | useless copies are made when evaluating nested expressions. Changes: - kill LazyBit, introduce EvalBeforeNestingBit and EvalBeforeAssigningBit - product and random don't evaluate immediately anymore - eval() always evaluates - change the value of Dynamic to some large positive value, in preparation of future simplifications
* -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")
* 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.
* rework Identity API: no longer restricted to square matricesGravatar Benoit Jacob2008-01-11
|
* -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
