* actually honor EIGEN_STACK_ALLOCATION.Gravatar Benoit Jacob2008-12-16
| | | | Can set it to 0 to disable stack alloc which guarantees that bad alloc throws exceptions if they are enabled.
* Fix memory alignment (hence vectorization) on MSVC thanks to help from Armin ↵Gravatar Benoit Jacob2008-12-15
| | | | Berres.
* Use an aligned IOFormat in the docsGravatar Benoit Jacob2008-12-06
|
* * fix compile error when C++0x is enabled: static_assert() needs ;Gravatar Benoit Jacob2008-12-06
| | | | | | thanks to devurandom for reporting * remove redundant ; in ei_internal_assert * minor fixes in InsideEigenExample.dox
* add internal documentationGravatar Benoit Jacob2008-11-30
|
* Update e-mail addressGravatar Benoit Jacob2008-11-24
|
* * add Gael a (c) line in IO.hGravatar Benoit Jacob2008-11-17
| | | | | * let user change default format by defining EIGEN_DEFAULT_IO_FORMAT * improve docs a little
* add Eigen namespace in EIGEN_INHERIT_ASSIGNMENT_OPERATORGravatar Gael Guennebaud2008-10-27

* Big API change in Cholesky module:Gravatar Gael Guennebaud2008-10-13
| | | | | | | | | | | | | | | | * rename Cholesky to LLT * rename CholeskyWithoutSquareRoot to LDLT * rename MatrixBase::cholesky() to llt() * rename MatrixBase::choleskyNoSqrt() to ldlt() * make {LLT,LDLT}::solve() API consistent with other modules Note that we are going to keep a source compatibility untill the next beta release. E.g., the "old" Cholesky* classes, etc are still available for some time. To be clear, Eigen beta2 should be (hopefully) source compatible with beta1, and so beta2 will contain all the deprecated API of beta1. Those features marked as deprecated will be removed in beta3 (or in the final 2.0 if there is no beta 3 !). Also includes various updated in sparse Cholesky.
* * move memory related stuff to util/Memory.hGravatar Gael Guennebaud2008-08-26
| | | | | * clean ugly doxygen inheritence of expressions * keep improving the documentation... slowly !
* * split Meta.h to Meta.h (generic meta programming) and XprHelper.h (relates ↵Gravatar Gael Guennebaud2008-08-24
| | | | | | | | | to eigen mechanism) * added a meta.cpp unit test * EIGEN_TUNE_FOR_L2_CACHE_SIZE now represents L2 block size in Bytes (whence the ei_meta_sqrt...) * added a CustomizeEigen.dox page * added a TOC to QuickStartGuide.dox
* * 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
* - remove the ASM macro as in fact Gael had been removing all the remainingGravatar Benoit Jacob2008-08-21
| | | | | | | | | asm("...") from the code while fixing MSVC compat (so your changes crossed one another). - move the pragma warning to CoreDeclarations, it's the right place to do early platform checks. CCMAIL:ps_ml@gmx.de
* patch by Patrick Spendrin: fix MSVC compatibilityGravatar Benoit Jacob2008-08-21

* * Fix CMakeLists.txt issue with SVDGravatar Gael Guennebaud2008-08-20
| | | | * Fix on stack memory allocation issues
* 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).
* only use alloca on linux. Use malloc on other platforms. Needed for mingwGravatar Benoit Jacob2008-08-18
| | | | compatibility.
* * add Regression module, from eigen1, improved, with doc and unit-test.Gravatar Benoit Jacob2008-08-11
| | | | | | | | | * fix .normalized() so that Random().normalized() works; since the return type became complicated to write down i just let it return an actual vector, perhaps not optimal. * add Sparse/CMakeLists.txt. I suppose that it was intentional that it didn't have CMakeLists, but in <=2.0 releases I'll just manually remove Sparse.
* * LU decomposition, supporting all rectangular matrices, with fullGravatar Benoit Jacob2008-08-04
| | | | | | | | | | pivoting for better numerical stability. For now the only application is determinant. * New determinant unit-test. * Disable most of Swap.h for now as it makes LU fail (mysterious). Anyway Swap needs a big overhaul as proposed on IRC. * Remnants of old class Inverse removed. * Some warnings fixed.
* Added MatrixBase::Unit*() static function to easily create unit/basis vectors.Gravatar Gael Guennebaud2008-07-19
| | | | | | | Removed EulerAngles, addes typdefs for Quaternion and AngleAxis, and added automatic conversions from Quaternion/AngleAxis to Matrix3 such that: Matrix3f m = AngleAxisf(0.2,Vector3f::UnitX) * AngleAxisf(0.2,Vector3f::UnitY); just works.
* * 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.
* * move some compile time "if" to their respective unroller (assign and dot)Gravatar Gael Guennebaud2008-06-07
| | | | | * fix a couple of compilation issues when unrolling is disabled * reduce default unrolling limit to a more reasonable value
* many small fixes and documentation improvements,Gravatar Benoit Jacob2008-05-29
| | | | this should be alpha5.
* * updated the assignement operator macro so that overloadsGravatar Gael Guennebaud2008-05-28
| | | | | | in MatrixBase work * removed product_selector and cleaned Product.h a bit * cleaned Assign.h a bit
* 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.
* - 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
* 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.
* * 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
* * 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.
* 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).
* * Add fixed-size template versions of corner(), start(), end().Gravatar Benoit Jacob2008-04-12
| | | | | | | * Use them to write an unrolled path in echelon.cpp, as an experiment before I do this LU module. * For floating-point types, make ei_random() use an amplitude of 1.
* - cleaner use of OpenMP (no code duplication anymore)Gravatar Benoit Jacob2008-04-11
| | | | | | | | | | | | | | using a macro and _Pragma. - use OpenMP also in cacheOptimalProduct and in the vectorized paths as well - kill the vector assignment unroller. implement in operator= the logic for assigning a row-vector in a col-vector. - CMakeLists support for building tests/examples with -fopenmp and/or -msse2 - updates in bench/, especially replace identity() by ones() which prevents underflows from perturbing bench results.
* * 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
