af27fb7590 Add cdash.org support:
* the dashboard is there: http://my.cdash.org/index.php?project=Eigen
* now you can run the tests from the top build dir
  and submit report like that (from the top build dir):
  ctest -D Experimental
* todo:
 - add some nighlty builds (I'll add a few on my computer)
 - add valgrind memory checks, performances tests, compilation time tests, etc.

cb71dc4bbf Add a vectorization_logic unit test for assign and sum.
Need to add dot and more tests, but it seems I've already
found some room for improvement in sum.

709e903335 Sparse module:
* extend unit tests
* add support for generic sum reduction and dot product
* optimize the cwise()* : this is a special case of CwiseBinaryOp where
  we only have to process the coeffs which are not null for *both* matrices.
  Perhaps there exist some other binary operations like that ?

dae7f065d4 didn't meant to commit the fortran check. but anyway, unfortunately it doesn't work the way iot should. the test fails and cmake will terminate if it doesn't find a fortran compiler 2009-01-05 14:40:27 +00:00

3958e7f751 add unit-test checking the assertion on unaligned arrays -- checking
that it's triggered when and only when it should.

4336cf3833 * add unit-tests to check allowed and forbiddent mixing of different scalar types
* fix issues in Product revealed by this test
* in Dot.h forbid mixing of different types (at least for now, might allow real.dot(complex) in the future).

94f6f2a7de Add an axis aligned box in the geometry module.
Some naming questions:
- for "extend" we could also think of: "expand", "union", "add"
- same for "clamp": "crop", "intersect"
- same for "contains": "isInside", "intersect"
=> ah "intersect" is conflicting, so that eliminates this one !

52406aecad * Extend a bit ParametrizedLine and move it to a separate file,
add unit-tests for it.
* remove "using namespace std" in test/main.h such that the compilation
  bug found today in SVD won't happen again.

f52d119b9c Solve a big issue with data alignment and dynamic allocation:
* add a WithAlignedOperatorNew class with overloaded operator new
* make Matrix (and Quaternion, Transform, Hyperplane, etc.) use it
  if needed such that "*(new Vector4) = xpr" does not failed anymore.
* Please: make sure your classes having fixed size Eigen's vector
  or matrice attributes inherit WithAlignedOperatorNew
* add a ei_new_allocator STL memory allocator to use with STL containers.
  This allocator really calls operator new on your types (unlike GCC's
  new_allocator). Example:
  std::vector<Vector4f> data(10);
  will segfault if the vectorization is enabled, instead use:
  std::vector<Vector4f,ei_new_allocator<Vector4f> > data(10);
NOTE: you only have to worry if you deal with fixed-size matrix types
with "sizeof(matrix_type)%16==0"...

ba100998bf * split Meta.h to Meta.h (generic meta programming) and XprHelper.h (relates to eigen mechanism)
* added a meta.cpp unit test
* EIGEN_TUNE_FOR_L2_CACHE_SIZE now represents L2 block size in Bytes (whence the ei_meta_sqrt...)
* added a CustomizeEigen.dox page
* added a TOC to QuickStartGuide.dox

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

104f8fd36e Added a SVD module:
- the decompostion code has been adfapted from JAMA
 - handles non square matrices of size MxN with M>=N
 - does not work for complex matrices
 - includes a solver where the parts corresponding to zero singular values are set to zero

a6d387a359 Various compilation fixes for MSVC 9. All tests compile but some
still fail at runtime in ei_aligned_free() (even without vectorization).

17ec407ccd * add Regression module, from eigen1, improved, with doc and unit-test.
* fix .normalized() so that Random().normalized() works; since the return
type became complicated to write down i just let it return an actual
vector, perhaps not optimal.
* add Sparse/CMakeLists.txt. I suppose that it was intentional that it
didn't have CMakeLists, but in <=2.0 releases I'll just manually remove
Sparse.

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

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
