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.

6e2c53e056 Added an automatically generated list of selected examples in the documentation.
Added the custom gemetry_module tag, and use it.

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.

c5bd1703cb change derived classes methods from "private:_method()"
to "public:method()" i.e. reimplementing the generic method()
from MatrixBase.
improves compilation speed by 7%, reduces almost by half the call depth
of trivial functions, making gcc errors and application backtraces
nicer...

25ba9f377c * add bench/benchVecAdd.cpp by Gael, fix crash (ei_pload on non-aligned)
* introduce packet(int), make use of it in linear vectorized paths
  --> completely fixes the slowdown noticed in benchVecAdd.
* generalize coeff(int) to linear-access xprs
* clarify the access flag bits
* rework api dox in Coeffs.h and util/Constants.h
* improve certain expressions's flags, allowing more vectorization
* fix bug in Block: start(int) and end(int) returned dyn*dyn size
* fix bug in Block: just because the Eval type has packet access
  doesn't imply the block xpr should have it too.

bb1f4e44f1 * Block: row and column expressions in the inner direction
now have the Like1D flag.

* Big renaming:
  packetCoeff ---> packet
  VectorizableBit ---> PacketAccessBit
  Like1DArrayBit ---> LinearAccessBit

310f7aa096 moved purely "array" related stuff to a new module Array.
This include:
 - cwise Pow,Sin,Cos,Exp...
 - cwise Greater and other comparison operators
 - .any(), .all() and partial reduction
 - random

486fdb26a1 many small fixes and documentation improvements,
this should be alpha5.

4317fad869 * Added several cast to int of the enums (needed for some compilers)
* Fix a mistake in CwiseNullary.
* Added a CoreDeclarions header that declares only the forward declarations
  and related basic stuffs.

678f18fce4 put inline keywords everywhere appropriate. So we don't need anymore to pass
-finline-limit=1000 to gcc to get good performance. By the way some cleanup.

46fa4c713f * Started support for unaligned vectorization.
* Introduce a new highly optimized matrix-matrix product for large
  matrices. The code is still highly experimental and it is activated
  only if you define EIGEN_WIP_PRODUCT at compile time.
  Currently the third dimension of the product must be a factor of
  the packet size (x4 for floats) and the right handed side matrix
  must be column major.
  Moreover, currently c = a*b; actually computes c += a*b !!
  Therefore, the code is provided for experimentation purpose only !
  These limitations will be fixed soon or later to become the default
  product implementation.

4c92150676 Added Triangular expression to extract upper or lower (strictly or not)
part of a matrix. Triangular also provide an optimised method for forward
and backward substitution. Further optimizations regarding assignments and
products might come later.

Updated determinant() to take into account triangular matrices.

Started the QR module with a QR decompostion algorithm.
Help needed to build a QR algorithm (eigen solver) based on it.

a451835bce Make the explicit vectorization much more flexible:
- support dynamic sizes
 - support arbitrary matrix size when the matrix can be seen as a 1D array
   (except for fixed size matrices where the size in Bytes must be a factor of 16,
    this is to allow compact storage of a vector of matrices)
Note that the explict vectorization is still experimental and far to be completely tested.
