* Big renaming:Gravatar Benoit Jacob2010-01-04
| | | | | | start ---> head end ---> tail Much frustration with sed syntax. Need to learn perl some day.
* make some changes to please clang, fix some warnings too.Gravatar Thomas Capricelli2010-01-04
|
* Fix #69 for the second time, and add the respective regression testGravatar Gael Guennebaud2010-01-04
|
* remove debug output. sorry!Gravatar Benoit Jacob2010-01-02
|
* clarify docs as requested on forumGravatar Benoit Jacob2010-01-02
|
* * Fix bug #79: ei_alignmentOffset was assuming that ptr is multiple ofGravatar Benoit Jacob2010-01-02
| | | | | | | sizeof(Scalar), and that assumption breaks with double on linux x86-32. * Rename ei_alignmentOffset to ei_first_aligned * Rewrite its documentation and part of its body * The variant taking a MatrixBase doesn't need a separate size argument.
* put the assign assert and debug info before the assignment itselfGravatar Benoit Jacob2010-01-01

* fix #75, and add a basic unit test for HessenbergGravatar Gael Guennebaud2009-12-23

* fix #69 and extend unit tests or triangular solversGravatar Gael Guennebaud2009-12-23

* support gcc 4.5Gravatar Benoit Jacob2009-12-21
|
* add missing inclusion of LU/arch, thanks to J.B. RouaultGravatar Gael Guennebaud2009-12-19
|
* oops, remove duplicated ctorGravatar Gael Guennebaud2009-12-19
|
* much better workaround for empty struct (the previous one caused GCC 4.3 to ↵Gravatar Gael Guennebaud2009-12-18
| | | | generate wrong code leading to segfaults)
* * introduce ei_alignmentOffset(MatrixBase&,Integer)Gravatar Benoit Jacob2009-12-16
| | | | | couldnt put it in Memory.h as it needs the definition of MatrixBase * make Redux use it
* this really fix the previous warningGravatar Gael Guennebaud2009-12-16

* fix warning by making ei_empty_struct::_ei_dummy_ privateGravatar Gael Guennebaud2009-12-16
|
* fix compilation when mixing typesGravatar Gael Guennebaud2009-12-16
|
* * fix aliasing checks when the lhs is also transposed. At the same time,Gravatar Gael Guennebaud2009-12-16
| | | | | | significantly simplify the code of these checks while extending them to catch much more expressions! * move the enabling/disabling of vectorized sin/cos to the architecture traits
* suppress unused variable warningsGravatar Gael Guennebaud2009-12-15
|
* no, this wasn't equivalent to ei_pload at all, after all!Gravatar Benoit Jacob2009-12-15
|
* Gael, who is a man of few words^Winstructions, is right, as usual.Gravatar Benoit Jacob2009-12-15
|
* Suppressed the warning for missing assignment generators (forgot that in the ↵Gravatar Hauke Heibel2009-12-15
| | | | | | last submission). Commented Quake3's fast inverser sqrt in SSE's MathFunction header.
* *use scalar instructions, packet not needed hereGravatar Benoit Jacob2009-12-14
| | | | *remove unused var warning
* only include SSE path if SSE enabledGravatar Benoit Jacob2009-12-14
|
* add SSE path for Matrix4f inverse, taken from Intel except that we do a kosherGravatar Benoit Jacob2009-12-14
| | | | | | division instead of RCPPS-followed-by-Newton-Raphson. The rationale for that is that elsewhere in Eigen we dont allow ourselves this approximation (which throws 2 bits of mantissa), so there's no reason we should allow it here.
* change the Arch constants: const int ---> enum, more explicit names, and useGravatar Benoit Jacob2009-12-14
| | | | of a namespace instead of Prefix_Name.
* Warning 4512 (assignment operators could not be generated) is now simply ↵Gravatar Hauke Heibel2009-12-14
| | | | | | disabled. All unimplemented assignment operators have been removed.
* Fixed a bad type conversion.Gravatar Hauke Heibel2009-12-13

* Correct type of ei_solve_retval<LLT,...>::operator=Gravatar Jitse Niesen2009-12-12
|
* Removed more warnings.Gravatar Hauke Heibel2009-12-12
|
* Added to possibility to compile unit tests at maximum warning level.Gravatar Hauke Heibel2009-12-12
| | | | Silenced (amongst others) many conversion related warnings.
* * 4x4 inverse: revert to cofactors methodGravatar Benoit Jacob2009-12-09
| | | | | | | * inverse tests: use createRandomMatrixOfRank, use more strict precision * tests: createRandomMatrixOfRank: support 1x1 matrices * determinant: nest the xpr * Minor: add comment
* Documentation clean up.Gravatar Jitse Niesen2009-12-08
| | | | | | | | * remove non-existant reference to CwiseAll * define \householder_module (used in HouseholderSequence.h) * update I01_TopicLazyEvaluation.dox - Product is now called GeneralProduct * remove reference to list of examples which was deleted ages ago * rename PartialLU_solve.cpp snippet to PartialPivLU_solve.cpp

| | | | | | | | | | | | | | | | | | * with random matrices multiplied by 1e+8 (i.e. fixed wrong absolute fuzzy compare) * with 10,000 repetitions (i.e. the fuzzy compare is really clever) and when it occasionnally fails, less than once in 10,000 repeats, it is only on the exact rank computation.
| * | Big reworking of ColPivQR and its unit test, which now passes even with ↵Gravatar Benoit Jacob2009-12-01
| | | | | | | | | | | | thousands of repetitions and correctly tests matrices of all sizes. Several surprises along the way: for example, a major cause of trouble was the optimized "table of column squared norms" where the accumulation of imprecision was a serious issue; another surprise is that tests like "x!=0" before dividing by x really benefit from being replaced by fuzzy tests, as i hit real cases where i got wrong results in 1/epsilon.
