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

1e62e0b0d8 more ET refactoring:
* extend Cwise for multiple storage base class
* a lot of cleaning in the Sparse module

c6822d6723 Added EIGEN_REF_TO_TEMPORARY define for rvalue support.
Allowed VC10 to make use of static_assert.

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

409e82be06 doc and use sed to clean the class hierarchy instead of
preprocessor directives.

00a8d314c5 * move memory related stuff to util/Memory.h
* clean ugly doxygen inheritence of expressions
* keep improving the documentation... slowly !

f729fc1d70 * Add the possibility to customize the output of matrices, e.g.:
IoFormat OctaveFmt(4, AlignCols, ", ", ";\n", "", "", "[", "]");
   cout << mat.format(OctaveFmt);
  The first "4" is the precision.
  Documentation missing.
* Some compilation fixes

4fa40367e9 * Big change in Block and Map:
- added a MapBase base xpr on top of which Map and the specialization
    of Block are implemented
  - MapBase forces both aligned loads (and aligned stores, see below) in expressions
    such as "x.block(...) += other_expr"
* Significant vectorization improvement:
 - added a AlignedBit flag meaning the first coeff/packet is aligned,
   this allows to not generate extra code to deal with the first unaligned part
 - removed all unaligned stores when no unrolling
 - removed unaligned loads in Sum when the input as the DirectAccessBit flag
* Some code simplification in CacheFriendly product
* Some minor documentation improvements

a41f2b4216 * fix bug in SwapWrapper : store the wrapped expression by reference
* optimize setIdentity: when the matrix is large enough it is better to
  setZero() and overwrite the diagonal
* start of LU solver, disabled for now

58ba9ca72f LU: remove partial-pivoting path (moderately useful since it's does
not allow to easily get the rank), fix a bug (which could have been
triggered by matrices having coefficients of very different
magnitudes).
Part: add an assert to prevent hard to find bugs
Swap: update comments

88bb2087c1 New implementation of Swap as discussed, reusing Assign. Makes LU run
10% faster overall.

c2f8ecf466 * LU decomposition, supporting all rectangular matrices, with full
pivoting for better numerical stability. For now the only application is
determinant.
* New determinant unit-test.
* Disable most of Swap.h for now as it makes LU fail (mysterious).
Anyway Swap needs a big overhaul as proposed on IRC.
* Remnants of old class Inverse removed.
* Some warnings fixed.

8463b7d3f4 * fix compilation issue in Product
* added some tests for product and swap
* overload .swap() for dynamic-sized matrix of same size

366971bea4 * start of the Geometry module with a cross product and quaternion expressions
(haven't tried them yet)
* applied the meta selector rule to MatrixBase::swap()

d1a29d6319 -new: recursive costs system, useful to determine automatically
when to evaluate arguments and when to meta-unroll.
-use it in Product to determine when to eval args. not yet used
 to determine when to unroll. for now, not used anywhere else but
 that'll follow.
-fix badness of my last commit

729618c945 * #define EIGEN_NDEBUG now also disables asserts. Useful
to disable eigen's asserts without disabling one's own program's
  asserts. Notice that Eigen code should now use ei_assert()
  instead of assert().
* Remove findBiggestCoeff() as it's now almost redundant.
* Improve echelon.cpp: inner for loop replaced by xprs.
* remove useless "(*this)." here and there. I think they were
  first introduced by automatic search&replace.
* fix compilation in Visitor.h (issue triggered by echelon.cpp)
* improve comment on swap().

2ee68a074e generalized ei_traits<>.
Finally the importing macro is named EIGEN_BASIC_PUBLIC_INTERFACE
because it does not only import the ei_traits, it also makes the base class
a friend, etc.

01572b9f54 big change: MatrixBase only takes one template parameter "Derived", the
template parameter "Scalar" is removed. This is achieved by introducting a
template <typename Derived> struct Scalar to achieve a forward-declaration of
the Scalar typedefs.

c67e717404 alpha 3.1. in this commit:
- finally get the Eval stuff right. get back to having Eval as
  a subclass of Matrix with limited functionality, and then,
  add a typedef MatrixType to get the actual matrix type.
- add swap(), findBiggestCoeff()
- bugfix by Ramon in Transpose
- new demo: doc/echelon.cpp
