* oops, didn't want to commit thatGravatar Benoit Jacob2009-05-07

* CREDIT Hauke Heibel, more std::vector::insert fixesGravatar Benoit Jacob2009-05-07
|
* More Cholesky fixes.Gravatar Benoit Jacob2009-04-01
| | | | | | | | | * Cholesky decs are NOT rank revealing so remove all the rank/isPositiveDefinite etc stuff. * fix bug in LLT: s/return/continue/ * introduce machine_epsilon constants, they are actually needed for Higman's formula determining the cutoff in Cholesky. Btw fix the page reference to his book (chat with Keir). * solve methods always return true, since this isn't a rank revealing dec. Actually... they already did always return true!! Now it's explicit. * updated dox and unit-test
* eventually c++ does not provide any optimized pow(int,int) function,Gravatar Gael Guennebaud2009-02-18
| | | | so here you go :) (should also fix Timothy's troubles)
* add MatrixBase::stableNorm() avoiding over/under-flowGravatar Gael Guennebaud2009-01-28
| | | | | using it in QR reduced the error of Keir test from 1e-12 to 1e-24 but that's much more expensive !
* add custom implementation of hypotGravatar Gael Guennebaud2009-01-07
|
* remove non standard hypotf function callGravatar Gael Guennebaud2009-01-07
|
* more Scalar conversions fixesGravatar Gael Guennebaud2009-01-07
|
* found one bug in the previous ++ changesGravatar Gael Guennebaud2008-12-17
|
* one more warning fix, thanks to Armin BerresGravatar Gael Guennebaud2008-12-12
|
* * fix a couple of warnings (patch from Armin Berres)Gravatar Gael Guennebaud2008-12-12
| | | | * allow Map to map null data
* Update e-mail addressGravatar Benoit Jacob2008-11-24
|
* * fix issues with "long double" type (useful to enforce the use of x87 ↵Gravatar Gael Guennebaud2008-09-14
| | | | | | registers) * extend the documentation on "extending Eigen"
* if EIGEN_NICE_RANDOM is defined, the random functions will return numbers withGravatar Benoit Jacob2008-09-01
| | | | | | few bits left of the comma and for floating-point types will never return zero. This replaces the custom functions in test/main.h, so one does not anymore need to think about that when writing tests.
* -fix certain #includesGravatar Benoit Jacob2008-05-12
| | | | -fix CMakeLists, public headers weren't getting installed
* * 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.
* * 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)
* * 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
* some cleaning in Cholesky and removed evil ei_sqrt of complexGravatar Gael Guennebaud2008-04-27
|
* * added ei_sqrt for complexGravatar Gael Guennebaud2008-04-27
| | | | | * updated Cholesky to support complex * correct result_type for abs and abs2 functors
* * 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.
* * 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().
* * 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
* - 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.
* 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.
* 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
* move Core/ to a src/ subdir, in preparation for following changesGravatar Benoit Jacob2007-12-28
