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

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

c1e2156d8a * Much better, consistent error msgs when mixing different scalar types:
- in matrix-matrix product, static assert on the two scalar types to be the same.
- Similarly in CwiseBinaryOp. POTENTIALLY CONTROVERSIAL: we don't allow anymore binary
  ops to take two different scalar types. The functors that we defined take two args
  of the same type anyway; also we still allow the return type to be different.
  Again the reason is that different scalar types are incompatible with vectorization.
  Better have the user realize explicitly what mixing different numeric types costs him
  in terms of performance.
  See comment in CwiseBinaryOp constructor.
- This allowed to fix a little mistake in test/regression.cpp, mixing float and double
- Remove redundant semicolon (;) after static asserts

3d90c13970 norm2() renamed to squaredNorm(), kept as deprecated for now. 2008-11-03 19:14:17 +00:00

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

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)

a172385720 Updated fuzzy comparisons to use L2 norm as all my experiments
tends to show L2 norm works very well here.
(the legacy implementation is still available via a preprocessor token
 to allow further experiments if needed...)

48262b9734 added a static assertion mechanism
(see notes in Core/util/StaticAssert.h for details)

9d8876ce82 * rename XprCopy -> Nested
* rename OperatorEquals -> Assign
* move Util.h and FwDecl.h to a util/ subdir

61e58cf602 fixes as discussed with Gael on IRC. Mainly, in Fuzzy.h, and Dot.h, use
ei_xpr_copy to evaluate args when needed. Had to introduce an ugly
trick with ei_unref as when the XprCopy type is a reference one can't
directly access member typedefs such as Scalar.

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.

6907886a15 prefix global functions with ei_ as previous solution was rather
fragile. also fix compilation with g++ 4.3.

5111ace0d6 move default parameter values from function definition to function declaration.
doxygen likes it and this fixes compilation on ICC.

84934ea217 - move: DerivedTraits becomes MatrixBase::Traits
- the static constants are private again in the Derived classes
- more documentation and code snippets
- new isDiagonal() method

d1d55e67e9 - make MatrixBase and all expressions aware of their preferred traversal order.
Honor this preference in operator=.
- add several methods to the API
- rework API for diagonal matrices
- add benchmarking code
