e77ccf2928 * Rewrite the triangular solver so that we can take advantage of our efficient matrix-vector products:
=> up to 6 times faster !
* Added DirectAccessBit to Part
* Added an exemple of a cwise operator
* Renamed perpendicular() => someOrthogonal() (geometry module)
* Fix a weired bug in ei_constant_functor: the default copy constructor did not copy
  the imaginary part when the single member of the class is a complex...

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.

05ad083467 Added MatrixBase::Unit*() static function to easily create unit/basis vectors.
Removed EulerAngles, addes typdefs for Quaternion and AngleAxis,
and added automatic conversions from Quaternion/AngleAxis to Matrix3 such that:
 Matrix3f m = AngleAxisf(0.2,Vector3f::UnitX) * AngleAxisf(0.2,Vector3f::UnitY);
just works.

f5791eeb70 the big Array/Cwise rework as discussed on the mailing list. The new API
can be seen in Eigen/src/Core/Cwise.h.

3b94436d2f * vectorize dot product, copying code from sum.
* make the conj functor vectorizable: it is just identity in real case,
  and complex doesn't use the vectorized path anyway.
* fix bug in Block: a 3x1 block in a 4x4 matrix (all fixed-size)
  should not be vectorizable, since in fixed-size we are assuming
  the size to be a multiple of packet size. (Or would you prefer
  Vector3d to be flagged "packetaccess" even though no packet access
  is possible on vectors of that type?)
* rename:
  isOrtho for vectors ---> isOrthogonal
  isOrtho for matrices ---> isUnitary
* add normalize()
* reimplement normalized with quotient1 functor

32c5ea388e work on rotations in the Geometry module:
- convertions are done trough constructors and operator=
 - added a EulerAngles class

bc0c7c57ed Added an extensible mechanism to support any kind of rotation
representation in Transform via the template static class
ToRotationMatrix.
Added a lightweight AngleAxis class (similar to Rotation2D).

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.

fbbd8afe30 Started a Transform class in the Geometry module to represent
homography.
Fix indentation in Quaternion.h

915587d03d * add CommaInitializer::finished to allow the use of (Matrix3() << v0, v1, v2).finished()
as an argument of a function. Other possibilities for the name could be "end" or "matrix" ??
* various update in Quaternion, in particular I added a lot of FIXME about the API options,
  these have to be discussed and fixed.
