* * fix a vectorization issue in ProductGravatar Gael Guennebaud2008-12-19
| | | | | | * use _mm_malloc/_mm_free on other platforms than linux of MSVC (eg., cygwin, OSX) * replace a lot of inline keywords by EIGEN_STRONG_INLINE to compensate for poor MSVC inlining
* 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
* 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 !
* Various compilation fixes for MSVC 9. All tests compile but someGravatar Gael Guennebaud2008-08-19
| | | | still fail at runtime in ei_aligned_free() (even without vectorization).
* * doc improvements in Cwise and PartialRedux:Gravatar Benoit Jacob2008-08-19
| | | | | | | | | - 33 new snippets - unfuck doxygen output in Cwise (issues with function macros) - more see-also links from outside, making Cwise more discoverable * rename matrixNorm() to operatorNorm(). There are many matrix norms (the L2 is another one) but only one is called the operator norm. Risk of confusion with keyword operator is not too scary after all.
* * 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
* Several compilation fixes for MSVC and NVCC, basically:Gravatar Gael Guennebaud2008-07-29
| | | | | | | | - added explicit enum to int conversion where needed - if a function is not defined as declared and the return type is "tricky" then the type must be typedefined somewhere. A "tricky return type" can be: * a template class with a default parameter which depends on another template parameter * a nested template class, or type of a nested template class
* 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.
* - many updates after Cwise changeGravatar Benoit Jacob2008-07-08
| | | | | - fix compilation in product.cpp with std::complex - fix bug in MatrixBase::operator!=
* 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.
* 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.
* add experimental code for sparse matrix:Gravatar Gael Guennebaud2008-06-23
| | | | | | | | - uses the common "Compressed Column Storage" scheme - supports every unary and binary operators with xpr template assuming binaryOp(0,0) == 0 and unaryOp(0) = 0 (otherwise a sparse matrix doesnot make sense) - this is the first commit, so of course, there are still several shorcommings !
* * 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
* * 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.
* 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 _*coeffRef members in NestedByValueGravatar Gael Guennebaud2008-05-28
| | | | | | * added ConjugateReturnType and AdjointReturnType that are type-defined to Derived& and Transpose<Derived> if the scalar type is not complex: this avoids abusive copies in the cache friendly Product
* * 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
* some documentation fixes (Cwise* and Cholesky)Gravatar Gael Guennebaud2008-05-22
|
* Fix compilation issues with MSVC and NVCC.Gravatar Gael Guennebaud2008-05-15
| | | | Added a few typedef of complex return types in MatrixBase (Needed by MSVC)
* 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.
* * Started support for unaligned vectorization.Gravatar Gael Guennebaud2008-05-05
| | | | | | | | | | | | | * Introduce a new highly optimized matrix-matrix product for large matrices. The code is still highly experimental and it is activated only if you define EIGEN_WIP_PRODUCT at compile time. Currently the third dimension of the product must be a factor of the packet size (x4 for floats) and the right handed side matrix must be column major. Moreover, currently c = a*b; actually computes c += a*b !! Therefore, the code is provided for experimentation purpose only ! These limitations will be fixed soon or later to become the default product implementation.
* fix flag and cost computations for nested expressionsGravatar Gael Guennebaud2008-05-01
|
* Fixed a couple of issues introduced in previous commits.Gravatar Gael Guennebaud2008-04-26
| | | | Added a test for Triangular.
* 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.
* * rename XprCopy -> NestedGravatar Benoit Jacob2008-04-10
| | | | | * rename OperatorEquals -> Assign * move Util.h and FwDecl.h to a util/ subdir
* fix priority operator bugs in the computationGravatar Gael Guennebaud2008-04-09
| | | | of the VectorizableBit flag, now benchmark.cpp is properly vectorized
* 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.
* * make use of the EvalBeforeNestingBit and EvalBeforeAssigningBitGravatar Gael Guennebaud2008-04-05
| | | | | | | | | | | in ei_xpr_copy and operator=, respectively. * added Matrix::lazyAssign() when EvalBeforeAssigningBit must be skipped (mainly internal use only) * all expressions are now stored by const reference * added Temporary xpr: .temporary() must be called on any temporary expression not directly returned by a function (mainly internal use only) * moved all functors in the Functors.h header * added some preliminaries stuff for the explicit vectorization
* * added cwise comparisonsGravatar Gael Guennebaud2008-04-03
| | | | | | | * added "all" and "any" special redux operators * added support bool matrices * added support for cost model of STL functors via ei_functor_traits (By default ei_functor_traits query the functor member Cost)
* -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
* * support for matrix-scalar quotient with integer scalar types.Gravatar Gael Guennebaud2008-03-21
| | | | | | * added cache efficient matrix-matrix product. - provides a huge speed-up for large matrices. - currently it is enabled when an explicit unrolling is not possible.
* - expand MathFunctions.h to provide more functions, like exp, log...Gravatar Benoit Jacob2008-03-14
| | | | | | | | | | | - add cwiseExp(), cwiseLog()... --> for example, doing a gamma-correction on a bitmap image stored as an array of floats is a simple matter of: Eigen::Map<VectorXf> m = VectorXf::map(bitmap,size); m = m.cwisePow(gamma); - apidoc improvements, reorganization of the \name's - remove obsolete examples - remove EIGEN_ALWAYS_INLINE on lazyProduct(), it seems useless.
* 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.
* * Added support for a comma initializer: mat.block(i,j,2,2) << 1, 2, 3, 4;Gravatar Gael Guennebaud2008-03-08
| | | | | | | | | | If the number of coefficients does not match the matrix size, then an assertion is raised. No support for xpr on the right side for the moment. * Added support for assertion checking. This allows to test that an assertion is indeed raised when it should be. * Fixed a mistake in the CwiseUnary example.
* * coefficient wise operators are more generic, with controllable result type.Gravatar Gael Guennebaud2008-03-06
| | | | | | - compatible with current STL's functors as well as with the extention proposal (TR1) * thanks to the above, Cast and ScalarMultiple have been removed * benchmark_suite is more flexible (compiler and matrix size)
* 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")
* * Added generic unary operators (replace Opposite and Conjugate)Gravatar Gael Guennebaud2008-03-03
* functor templates are not template template parameter anymore (this allows to make templated functors !) * Main page: extented compiler discussion * A small hack to support gcc 3.4 and 4.0 (see the main page) * Fix a cast type issue in Cast * Various doxygen updates (mainly Cwise stuff and added doxygen groups in MatrixBase to split the huge memeber list, still not perfect though) * Updated Gael's email address
