d6e88f8155 * add LU unit-test. Seems like we have very good numerical stability!
* some cleanup, and grant me a copyright line on the determinant test.

681e944670 *implement LU solver (solves any rectangular system)
*in test/CMakeLists : modify EI_ADD_TEST so that 2nd argument is
additional compiler flags. used to add -O2 to test_product_large so it
doesn't take forever.

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.

55aeb1f83a Optimizations:
* faster matrix-matrix and matrix-vector products (especially for not aligned cases)
 * faster tridiagonalization (make it using our matrix-vector impl.)
Others:
 * fix Flags of Map
 * split the test_product to two smaller ones

8a967fb17c * implement slice vectorization. Because it uses unaligned
packet access, it is not certain that it will bring a performance
  improvement: benchmarking needed.
* improve logic choosing slice vectorization.
* fix typo in SSE packet math, causing crash in unaligned case.
* fix bug in Product, causing crash in unaligned case.
* add TEST_SSE3 CMake option.

54238961d6 * added a pseudo expression Array giving access to:
- matrix-scalar addition/subtraction operators, e.g.:
       m.array() += 0.5;
   - matrix/matrix comparison operators, e.g.:
      if (m1.array() < m2.array()) {}
* fix compilation issues with Transform and gcc < 4.1

f07f907810 Add QR and Cholesky module instantiations in the lib.
To try it with the unit tests set the cmake variable TEST_LIB to ON.

d5cbb1d002 added a unit test for Inverse
discovered that m1 == m1.inverse().inverse() fails though
m1.inverse()*m1 == I

64169389ed added an *optional* Eigen2 dynamic library.
it allows the possiblity to save some compilation time by linking to it
*and* defining the token EIGEN_EXTERN_INSTANCIATIONS

b501e08d81 now the unit-tests (hence all of Eigen) don't depend on Qt at all
anymore.

aebecae510 * find the proper way of nesting the expression in Flagged:
finally that's more subtle than just using ei_nested, because when
  flagging with NestByValueBit we want to store the expression by value
  already, regardless of whether it already had the NestByValueBit set.
* rename temporary() ----> nestByValue()
* move the old Product.h to disabled/, replace by what was ProductWIP.h
* tweak -O and -g flags for tests and examples
* reorder the tests -- basic things go first
* simplifications, e.g. in many methoeds return derived() and count on
  implicit casting to the actual return type.
* strip some not-really-useful stuff from the heaviest tests

559233c73e * fix the QR module to use extract/part instead of the previous triangular stuff
* added qr and eigensolver tests
* fix a compilation warning in Matrix copy constructor

522e24f2d7 update of the testing framework:
replaced the QTestLib framework my custom macros
and a (optional) custom script to run the tests from ctest.

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.

a2f8d4be6a Patch by Gael Guennebaud: coeff-wise binary operators.
This unifies + and - and moreover this patch introduces
coeff-wise * and / based on this. Also, corresponding test.

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.

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.

After huge thread on eigen mailing list, it appears that i'm the
only one in favor of prefix Ei. Everybody else prefers namespace
Eigen like we did in Eigen 1. So, revert.

Also add a macro USING_EIGEN_DATA_TYPES that application programmers
can use to automatically do "using"on the Matrix class and its
matrix/vector typedefs:
using Eigen::Matrix;
using Eigen::Matrix2d;
using Eigen::Vector2d;
... (the list of typedefs is really long).

thanks to the suffixes, the Vector typedefs aren't really polluting.

P.S. Danny, please skip this one :) I know you already reported the
namespace->prefix move, now that one would be too much noise :)
