* * 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
* 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.
* * more cleaning in ProductGravatar Gael Guennebaud2008-06-19
| | | | | | * make Matrix2f (and similar) vectorized using linear path * fix a couple of warnings and compilation issues with ICC and gcc 3.3/3.4 (cannot get Transform compiles with gcc 3.3/3.4, see the FIXME)
* Introduce generic Flagged xpr, remove already Lazy.h and Temporary.hGravatar Benoit Jacob2008-05-14
| | | | Rename DefaultLostFlagMask --> HerediraryBits
* * Added several cast to int of the enums (needed for some compilers)Gravatar Gael Guennebaud2008-05-12
| | | | | | * Fix a mistake in CwiseNullary. * Added a CoreDeclarions header that declares only the forward declarations and related basic stuffs.
* 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
* 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
* - introduce sum() returning the sum of the coeffs of a vectorGravatar Benoit Jacob2008-03-15
| | | | | - reimplement trace() as just diagonal().sum() - apidoc fixes
* 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
|
* 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.
* 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
* 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
