39ac57fa6d Big renaming: 
start ---> head
  end   ---> tail
Much frustration with sed syntax. Need to learn perl some day.

d02eccf584 add SSE path for Matrix4f inverse, taken from Intel except that we do a kosher 
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.

832045d363 Warning 4512 (assignment operators could not be generated) is now simply disabled. 
All unimplemented assignment operators have been removed.

d088ee35f6 Added to possibility to compile unit tests at maximum warning level. 
Silenced (amongst others) many conversion related warnings.

d2e44f2636 * 4x4 inverse: revert to cofactors method 
* inverse tests: use createRandomMatrixOfRank, use more strict precision
* tests: createRandomMatrixOfRank: support 1x1 matrices
* determinant: nest the xpr
* Minor: add comment

44d0d667cd 4x4 inverse: 
* change block selection threshold from 1e-2 to 1e-1

e3d890bc5a Another big refactoring change: 
* add a new Eigen2Support module including Cwise, Flagged, and some other deprecated stuff
* add a few cwiseXxx functions
* adapt a few modules to use cwiseXxx instead of the .cwise() prefix

2840ac7e94 big huge changes, so i dont remember everything. 
* renaming, e.g. LU ---> FullPivLU
* split tests framework: more robust, e.g. dont generate empty tests if a number is skipped
* make all remaining tests use that splitting, as needed.
* Fix 4x4 inversion (see stable branch)
* Transform::inverse() and geo_transform test : adapt to new inverse() API, it was also trying to instantiate inverse() for 3x4 matrices.
* CMakeLists: more robust regexp to parse the version number
* misc fixes in unit tests

ec02388a5d big rewrite in Inverse.h 
in particular, the API is essentially finalized and the 4x4 case is fixed to be numerically stable.

13f31b8daf * make PartialLU avoid to generate inf/nan when given a singular matrix 
(result undefined, but at least it won't take forever on intel 387)
* add lots of comments, especially to LU.h
* fix stuff I had broken in Inverse.h
* split inverse test

47eeb40380 remove the m_originalMatrix member. Instead, image() now takes the original matrix as parameter. It was the only method to use it anyway. Introduce m_isInitialized. 2009-10-18 15:21:19 -04:00

8332c232db big huge changes in LU! 
* continue the decomposition until a pivot is exactly zero;
  don't try to compute the rank in the decomposition itself.
* Instead, methods such as rank() use a new internal parameter
  called 'threshold' to determine which pivots are to be
  considered nonzero.
* The threshold is by default determined by defaultThreshold()
  but the user can override that by calling useThreshold(value).
* In solve/kernel/image, don't assume that the diagonal of U
  is sorted in decreasing order, because that's only approximately
  true. Additional work was needed to extract the right pivots.

e82ab8a5dd move also inverse() to ReturnByValue, by doing a solve on NestByValue<Identity>. 
also: adding resize() to MatrixBase was really needed ;)

4f9e270343 * make LU::kernel() and LU::image() also use ReturnByValue 
* make them return zero vector in the degenerate case, instead of asserting
  (let's stick to the principle that we only assert on memory errors)
