cff5e3ce9c Make use of the LazyBit, introduce .lazy(), remove lazyProduct. 2008-03-31 16:20:06 +00:00

f279162ec4 * introducte recursive Flags system for the expressions 
-- currently 3 flags: RowMajor, Lazy and Large
 -- only RowMajor actually used for now
* many minor improvements

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.

f64311e07d Extended the comma initializer to support xpr on the right side: 
Matrix3i mat; Vector2i vec(33,66);
  mat << vec.transpose(), 99,
         vec, Matrix2i::random();

721626dfc5 * Added support for a comma initializer: mat.block(i,j,2,2) << 1, 2, 3, 4; 
If the number of coefficients does not match the matrix size, then an assertion is raised.
  No support for xpr on the right side for the moment.

* Added support for assertion checking. This allows to test that an assertion is indeed raised
  when it should be.

* Fixed a mistake in the CwiseUnary example.

8e0d548039 * Fix a compilation issue with large fixed-size matrices: the unrollers were always instanciated. 
* the unrolling limits are configurable at compile time.

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

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

dad245af56 - eigen2 now fully enforces constness! found a way to achieve that 
with minimal code duplication. There now are only two (2)
  const_cast remaining in the whole source code.
- eigen2 now fully allows copying a row-vector into a column-vector.
  added a unit-test for that.
- split unit tests, improve docs, various improvements.

04502cccd9 rename Block to DynBlock and rework API to make place for 
upcoming fixed-size Block matrix. Also some cleanup.

346c00f4c8 Rework the unit-tests to use lower precision, so as to eliminate 
false positives. Also some cleanup in the fuzzy compares.

f355ef2df0 Merge WrapArray into FromArray. Less code. The downside is that we're using one more 
const_cast. But I think that anyway trying to maintain const strictness in Eigen2 is not
worth the hassle.

Konstantin: so the code snippet I sent you won't work anymore, replace wrapArray with fromArray.

e445f5085a implement the first _real_ unit-tests, testing the results for correctness instead 
of just checking compilation.

Fix the many issues discovered by these unit-tests, by the way fixing a performance bug.
