1578421ed1 fix issue #25 : the problem was that we assumed Dynamic was a multiple of a packet size 
(also disable the test of blueNorm)

a2087cd7a3 Add an efficient rank2 update function (like the level2 blas xSYR2 routine). 
Note that it is already used in Tridiagonalization.

9d5728c511 fix #4 
and also improve performance of Tridiag::diag/subDiag at the same time

6347b1db5b remove sentence "Eigen itself is part of the KDE project." 
it never made very precise sense. but now does it still make any?

9afd1324fd constant Diagonal ---> DiagonalBits 
introduce ei_is_diagonal to check for it
DiagonalCoeffs ---> Diagonal and allow Index to by Dynamic
-> add MatrixBase::diagonal(int) with unittest and doc

89f468671d * replace postfix ++ by prefix ++ wherever that makes sense in Eigen/ 
* fix some "unused variable" warnings in the tests; there remains a libstdc++ "deprecated"
warning which I haven't looked much into
 2008-12-17 14:30:01 +00:00

582c1f92c8 doc: add a "non stable" warning for parts which are not part 
of the stable API yet and a couple of other minor doc updates...

a6d387a359 Various compilation fixes for MSVC 9. All tests compile but some 
still fail at runtime in ei_aligned_free() (even without vectorization).

55aeb1f83a Optimizations: 
* faster matrix-matrix and matrix-vector products (especially for not aligned cases)
 * faster tridiagonalization (make it using our matrix-vector impl.)
Others:
 * fix Flags of Map
 * split the test_product to two smaller ones

172000aaeb Add .perpendicular() function in Geometry module (adapted from Eigen1) 
Documentation:
 * add an overview for each module.
 * add an example for .all() and Cwise::operator<

c10f069b6b * Merge Extract and Part to the Part expression. 
Renamed "MatrixBase::extract() const" to "MatrixBase::part() const"
* Renamed static functions identity, zero, ones, random with an upper case
  first letter: Identity, Zero, Ones and Random.

0ee6b08128 * split Product to a DiagonalProduct template specialization 
to optimize matrix-diag and diag-matrix products without
  making Product over complicated.
* compilation fixes in Tridiagonalization and HessenbergDecomposition
  in the case of 2x2 matrices.
* added an Orientation2D small class with similar interface than Quaternion
  (used by Transform to handle 2D and 3D orientations seamlessly)
* added a couple of features in Transform.

f07f907810 Add QR and Cholesky module instantiations in the lib. 
To try it with the unit tests set the cmake variable TEST_LIB to ON.

e3fac69f19 Added a Hessenberg decomposition class for both real and complex matrices. 
This is the first step towards a non-selfadjoint eigen solver.
Notes:
 - We might consider merging Tridiagonalization and Hessenberg toghether ?
 - Or we could factorize some code into a Householder class (could also be shared with QR)

4dd57b585d * rewrite of the QR decomposition: 
- works for complex
  - allows direct access to the matrix R
* removed the scale by the matrix dimensions in MatrixBase::isMuchSmallerThan(scalar)

2126baf9dc add an optimized path for the tridiagonalization of a 3x3 matrix. 
(useful for plane fitting, and covariance analysis of 3D data)

(see notes in Core/util/StaticAssert.h for details)

001b01a290 Rewrite from scratch of the eigen solver for symmetric matrices 
which now supports selfadjoint matrix. The implementation follows
Golub's famous book.

06752b2b77 * added a Tridiagonalization class for selfadjoint matrices 
* added MatrixBase::real()
* added the ability to extract a selfadjoint matrix from the
  lower or upper part of a matrix, e.g.:
    m.extract<Upper|SelfAdjoint>()
  will ignore the strict lower part and return a selfadjoint.
  This is compatible with ZeroDiag and UnitDiag.
