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

68d48511b2 move PartialLU to the new API 2009-10-21 17:06:42 -04:00

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

9a700c2974 * LU unit test: finally test fixed sizes 
* ReturnByValue: after all don't eval to temporary for generic MatrixBase impl

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

d71c7f42d3 * useThreshold -> setThreshold 
* remove defaultThreshold()

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.

f4661e696e Resize is only defined in Matrix and not in MatrixBase. 
I am not sure whether the better fix is to move the resize functions to MatrixBase.

904f35d194 discard vectorization in matrix-vector product when data is not even 
aligned on the scalar type size (e.g., for double on 32 bits system without -malign-double)

bb1cc0d092 after all we're not aligning to 8byte boundary 
keep most of the changes though as they make the code more extensible

d41577819b we were already aligning to 16 byte boundary fixed-size objects that are multiple of 16 bytes; 
now we also align to 8byte boundary fixed-size objects that are multiple of 8 bytes.
That's only useful for now for double, not e.g. for Vector2f, but that didn't seem to hurt. Am I missing something? Do you prefer that we don't align Vector2f at all?
Also, improvements in test_unalignedassert.

fa65b09661 add outerproduct coeff(int,int) method. 
This is needed to make this expression work:
(vec1*vec2.transpose())*vec3
Gael, no objection? Seems to make sense as that's fast.

eeabd18afc Fix compilation of HouseholderQR and ColPivotingHouseholderQR for non-square fixed-size matrices. 
For Colpiv that was just changing MatrixQType to MatrixType in the instantiation of HouseholderSequence.
For HouseholderQR I also re-ported the solve method from Colpiv as there were multiple issues.

765600458b * bump to 2.90.0 now that it's agreed that we're doing eigen3 
---> question: do we change the prefix eigen2/ to eigen3/ now?
       no, better wait until we've also changed the repository name
* more message improvements: "Install Eigen" was unclear as it left
  out other things like the BLAS library

92480ffd26 * Introduce make targets btest (build tests), blas (build blas lib), demos (build demos). 
* remove EIGEN_BUILD_TESTS and siblings
* add summary at the end of cmake run, hopefully not too verbose
* fix build of quaternion demo
* kill remnants of old binary library option

924b55e9a9 when copying a ReturnByValue into a MatrixBase, first eval it to a PlainMatrixType. 
This allows to limit the number of instantiations of the big template method evalTo.
Also allows to get rid of the dummy MatrixBase::resize().
See "TODO" comment.

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
