* * Add the possibility to customize the output of matrices, e.g.:Gravatar Gael Guennebaud2008-08-21
| | | | | | | | IoFormat OctaveFmt(4, AlignCols, ", ", ";\n", "", "", "[", "]"); cout << mat.format(OctaveFmt); The first "4" is the precision. Documentation missing. * Some compilation fixes
* renamed inverseProduct => solveTriangularGravatar Gael Guennebaud2008-08-09

* * 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
* fix compile errors with gcc 4.3: unresolved func call toGravatar Benoit Jacob2008-08-03

* * Rewrite the triangular solver so that we can take advantage of our ↵Gravatar Gael Guennebaud2008-07-26
| | | | | | | | | | | efficient matrix-vector products: => up to 6 times faster ! * Added DirectAccessBit to Part * Added an exemple of a cwise operator * Renamed perpendicular() => someOrthogonal() (geometry module) * Fix a weired bug in ei_constant_functor: the default copy constructor did not copy the imaginary part when the single member of the class is a complex...
* * Merge Extract and Part to the Part expression.Gravatar Gael Guennebaud2008-07-21
| | | | | | Renamed "MatrixBase::extract() const" to "MatrixBase::part() const" * Renamed static functions identity, zero, ones, random with an upper case first letter: Identity, Zero, Ones and Random.
* Add a *very efficient* evaluation path for both col-major matrix * vectorGravatar Gael Guennebaud2008-07-12
| | | | | | and vector * row-major products. Currently, it is enabled only is the matrix has DirectAccessBit flag and the product is "large enough". Added the respective unit tests in test/product/cpp.
* * added optimized paths for matrix-vector and vector-matrix productsGravatar Gael Guennebaud2008-07-09
| | | | | | (using either a cache friendly strategy or re-using dot-product vectorized implementation) * add LinearAccessBit to Transpose
* 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.
* split sum away from redux and vectorize it.Gravatar Benoit Jacob2008-06-23
| | | | | | (could come back to redux after it has been vectorized, and could serve as a starting point for that) also make the abs2 functor vectorizable (for real types).
* * split Product to a DiagonalProduct template specializationGravatar Gael Guennebaud2008-06-15
| | | | | | | | | | to optimize matrix-diag and diag-matrix products without making Product over complicated. * compilation fixes in Tridiagonalization and HessenbergDecomposition in the case of 2x2 matrices. * added an Orientation2D small class with similar interface than Quaternion (used by Transform to handle 2D and 3D orientations seamlessly) * added a couple of features in Transform.
* Add QR and Cholesky module instantiations in the lib.Gravatar Gael Guennebaud2008-06-14
| | | | To try it with the unit tests set the cmake variable TEST_LIB to ON.
* work around Doxygen bug triggered by r814874, which caused many classes to ↵Gravatar Benoit Jacob2008-06-02
| | | | | | disappear from the docs.
* added an *optional* Eigen2 dynamic library.Gravatar Gael Guennebaud2008-05-31
| | | | | it allows the possiblity to save some compilation time by linking to it *and* defining the token EIGEN_EXTERN_INSTANCIATIONS
* 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 ArrayBit to get the ability to manipulate a Matrix like a simple scalar.Gravatar Gael Guennebaud2008-05-29
| | | | In particular this flag changes the behavior of operator* to a coeff wise product.
* hehe, the complicated nesting scheme in Flagged in the previous commitGravatar Benoit Jacob2008-05-28
| | | | | | | | | | | was a sign that we were doing something wrong. In fact, having NestByValue as a special case of Flagged was wrong, and the previous commit, while not buggy, was inefficient because then when the resulting NestByValue xpr was nested -- hence copied -- the original xpr which was already nested by value was copied again; hence instead of 1 copy we got 3 copies. The solution was to ressuscitate the old Temporary.h (renamed NestByValue.h) as it was the right approach.
* * 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
* part 2 of big change: rename Triangular.h -> Extract.hGravatar Benoit Jacob2008-05-27
| | | | (svn required to commit that separately)
* - introduce Part and Extract classes, splitting and extending the formerGravatar Benoit Jacob2008-05-27
| | | | | | | | | | Triangular class - full meta-unrolling in Part - move inverseProduct() to MatrixBase - compilation fix in ProductWIP: introduce a meta-selector to only do direct access on types that support it. - phase out the old Product, remove the WIP_DIRTY stuff. - misc renaming and fixes
* 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.
* * 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)
* move arch-specific code to arch/SSE and arch/AltiVec subdirs.Gravatar Benoit Jacob2008-05-12
| | | | rename the noarch PacketMath.h to DummyPacketMath.h
* * Give Konstantinos a copyright lineGravatar Benoit Jacob2008-05-12
| | | | | | | | * Fix compilation of Inverse.h with vectorisation * Introduce EIGEN_GNUC_AT_LEAST(x,y) macro doing future-proof (e.g. gcc v5.0) check * Only use ProductWIP if vectorisation is enabled * rename EIGEN_ALWAYS_INLINE -> EIGEN_INLINE with fall-back to inline keyword * some cleanup/indentation
* only include SSE3 headers if compiling with SSE3 supportGravatar Benoit Jacob2008-05-08
|
* * 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.
* * split PacketMath.h to SSE and Altivec specific filesGravatar Gael Guennebaud2008-05-05
| | | | | * improved the flexibility of the new product implementation, now all sizes seems to be properly handled.
* * 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.
* * Patch by Konstantinos Margaritis: AltiVec vectorization.Gravatar Benoit Jacob2008-05-03
| | | | * Fix several warnings, temporarily disable determinant test.
* Removed ei_pload1, use posix_memalign to allocate aligned memory,Gravatar Gael Guennebaud2008-05-02
| | | | | and make Product ok when only one side is vectorizable (and the product is still vectorized)
* Added triangular assignement, e.g.:Gravatar Gael Guennebaud2008-04-26
| | | | | | | | | | | m.upper() = a+b; only updates the upper triangular part of m. Note that: m = (a+b).upper(); updates all coefficients of m (but half of the additions will be skiped) Updated back/forward substitution to better use Eigen's capability.
* 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.
* Make the explicit vectorization much more flexible:Gravatar Gael Guennebaud2008-04-25
| | | | | | | | - support dynamic sizes - support arbitrary matrix size when the matrix can be seen as a 1D array (except for fixed size matrices where the size in Bytes must be a factor of 16, this is to allow compact storage of a vector of matrices) Note that the explict vectorization is still experimental and far to be completely tested.
* 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.
* give up on OpenMP... for nowGravatar Benoit Jacob2008-04-18
|
* * Start of the LU module, with matrix inversion already there andGravatar Benoit Jacob2008-04-14
| | | | | | fully optimized. * Even if LargeBit is set, only parallelize for large enough objects (controlled by EIGEN_PARALLELIZATION_TRESHOLD).
* Merge Gael's experimental OpenMP parallelization support into Assign.h.Gravatar Benoit Jacob2008-04-11
|
* added a vectorized version of Product::_cacheOptimalProduct,Gravatar Gael Guennebaud2008-04-10
| | | | | added the possibility to disable the vectorization using EIGEN_DONT_VECTORIZE (some architectures has SSE support by default)
* * add typedefs for matrices/vectors with LargeBitGravatar Benoit Jacob2008-04-10
| | | | | | | | * add -pedantic to CXXFLAGS * cleanup intricated expressions with && and || which gave warnings because of "missing" parentheses * fix compile error in NumTraits, apparently discovered by -pedantic
* split those files in util/Gravatar Benoit Jacob2008-04-10
| | | | some more renaming
* * 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.
* * 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
* - remove Eval/EvalOMP (moving them to a disabled/ subdir in orderGravatar Benoit Jacob2008-03-31
| | | | | | | to preserve SVN history). They are made useless by the new ei_eval_unless_lazy. - introduce a generic Eval member typedef so one can do e.g. T t; U u; Product<T, U>::Eval m; m = t*u;
* Make use of the LazyBit, introduce .lazy(), remove lazyProduct.Gravatar Benoit Jacob2008-03-31
|
* * add Gael copyright lines on 2 more filesGravatar Benoit Jacob2008-03-26
| | | | | | | * macro renaming: EIGEN_NDEBUG becomes EIGEN_NO_DEBUG as this is much better (and similar to Qt) and EIGEN_CUSTOM_ASSERT becomes EIGEN_USE_CUSTOM_ASSERT * protect Core header by a EIGEN_CORE_H
* * Added a generic *redux* mini framework allowing custom redux operationsGravatar Gael Guennebaud2008-03-16
| | | | | | | | | | | | | | | as well as partial redux (vertical or horizontal redux). Includes shortcuts for: sum, minCoeff and maxCoeff. There is no shortcut for the partial redux. * Added a generic *visitor* mini framework. A visitor is a custom object sequentially applied on each coefficient with knowledge of its value and coordinates. It is currentlly used to implement minCoeff(int*,int*) and maxCoeff(int*,int*). findBiggestCoeff is now a shortcut for "this->cwiseAbs().maxCoeff(i,j)" * Added coeff-wise min and max. * fixed an issue with ei_pow(int,int) and gcc < 4.3 or ICC
* - introduce sum() returning the sum of the coeffs of a vectorGravatar Benoit Jacob2008-03-15
| | | | | - reimplement trace() as just diagonal().sum() - apidoc fixes
