* EIGEN_MAKE_ALIGNED_OPERATOR_NEW didn't actually need to get the classGravatar Benoit Jacob2009-01-08
| | | | name as parameter
* the big memory changes. the most important changes are:Gravatar Benoit Jacob2009-01-08
| | | | | | | ei_aligned_malloc now really behaves like a malloc (untyped, doesn't call ctor) ei_aligned_new is the typed variant calling ctor EIGEN_MAKE_ALIGNED_OPERATOR_NEW now takes the class name as parameter

* Sparse module:Gravatar Gael Guennebaud2009-01-07
| | | | | | | | * 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 ?
* * re-enabled deprecation warning on msvc now that eigen isn't using ↵Gravatar Kenneth Frank Riddile2009-01-07

* * introduce macros to replace inheritance for operator new overloadingGravatar Benoit Jacob2009-01-06
| | | | | | | | | (former solution still available and tested) This plays much better with classes that already have base classes -- don't force the user to mess with multiple inheritance, which gave much trouble with MSVC. * Expand the unaligned assert dox page * Minor fixes in the lazy evaluation dox page
* ...so the placement new is really trivial:)Gravatar Benoit Jacob2009-01-05

|
* gaaaaaaaaaaaaaaaaaahGravatar Benoit Jacob2009-01-05
| | | | | | | can't believe that 3 people wasted so much time because of a missing & !!!!! and this time MSVC didn't catch it so it was really copying the vector on the stack at an unaligned location!
* problem solved, we really want public inheritance and it is onlyGravatar Benoit Jacob2009-01-05
| | | | automatic when the _child_ class is a struct.
* the empty base class optimization is not standard. Most compilers implement ↵Gravatar Benoit Jacob2009-01-05
| | | | | | | a basic form of it; however MSVC won't implement it if there is more than one empty base class. For that reason, we shouldn't give Matrix two empty base classes, since sizeof(Matrix) must be optimal. So we overload operator new and delete manually rather than inheriting an empty struct for doing that.
* *fix compilation with MSVC 2005 in the Transform::construct_from_matrixGravatar Benoit Jacob2009-01-05
| | | | *fix warnings with MSVC 2005: converting M_PI to float gives loss-of-precision warnings

* * the 4th template param of Matrix is now Options. One bit for storageGravatar Benoit Jacob2009-01-04
| | | | | | | | | | | | | | | | order, one bit for enabling/disabling auto-alignment. If you want to disable, do: Matrix<float,4,1,Matrix_DontAlign> The Matrix_ prefix is the only way I can see to avoid ambiguity/pollution. The old RowMajor, ColMajor constants are deprecated, remain for now. * this prompted several improvements in matrix_storage. ei_aligned_array renamed to ei_matrix_array and moved there. The %16==0 tests are now much more centralized in 1 place there. * unalignedassert test: updated * update FindEigen2.cmake from KDElibs * determinant test: use VERIFY_IS_APPROX to fix false positives; add testing of 1 big matrix
* * In LU solvers: no need anymore to use row-major matricesGravatar Benoit Jacob2009-01-03
| | | | | | | | * Matrix: always inherit WithAlignedOperatorNew, regardless of vectorization or not * rename ei_alloc_stack to ei_aligned_stack_alloc * mixingtypes test: disable vectorization as SSE intrinsics don't allow mixing types and we just get compile errors there.
* Added a SparseVector class (not tested yet)Gravatar Gael Guennebaud2009-01-02

* fix the nomalloc test: it didn't catch the ei_stack_alloc inGravatar Benoit Jacob2008-12-31
| | | | | | | | | | | cachefriendlyproduct, that should be banned as well as depending on the platform they can give a malloc, and they could happen even with (large enough) fixed size matrices. Corresponding fix in Product.h: cachefriendly is now only used for dynamic matrices -- fixedsize, no matter how large, doesn't use the cachefriendly product. We don't need to care (in my opinion) about performance for large fixed size, as large fixed size is a bad idea in the first place and it is more important to be able to guarantee clearly that fixed size never causes a malloc.

| | | | | | | | * actually GCC 4.3.0 has a bug, "deprecated" placed at the end of a function prototype doesn't have any effect, moving them to the start of the function prototype makes it actually work! * finish porting the cholesky unit-test to the new LLT/LDLT, after the above fix revealed a deprecated warning
