* make the std::vector fix work also with dynamic size Eigen objects, e.g.Gravatar Benoit Jacob2009-01-10

* oops, fix compilation (sorry for all that noise!)Gravatar Benoit Jacob2009-01-09

* overloaded operator delete should call ei_conditinal_aligned_free, notGravatar Benoit Jacob2009-01-09
| | | | ei_aligned_free
* 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
* remove the Matrix_ prefixGravatar Benoit Jacob2009-01-06
|
* * 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
|
* oops, placement new should take a void*Gravatar Benoit Jacob2009-01-05
|
* we also had to overload the placement new... issue uncovered by Tim whenGravatar Benoit Jacob2009-01-05

* 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.
* *add PartialRedux::cross() with unit testGravatar Benoit Jacob2009-01-05
| | | | | *add transform-from-matrices test *undo an unwanted change in Matrix
* fix compilation on apple: _mm_malloc was undefined. the fix is to just use ↵Gravatar Benoit Jacob2009-01-05

* Fix bug in Matrix, in determining whether to overload operator new with an ↵Gravatar Benoit Jacob2009-01-04
| | | | aligned one, introduced in r905543
* * 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.
* * fix a vectorization issue in ProductGravatar Gael Guennebaud2008-12-19
| | | | | | * use _mm_malloc/_mm_free on other platforms than linux of MSVC (eg., cygwin, OSX) * replace a lot of inline keywords by EIGEN_STRONG_INLINE to compensate for poor MSVC inlining
* * fix in IO.h, a useless copy was made because of assignment fromGravatar Benoit Jacob2008-12-18
| | | | | | | | | | | | | | | Derived to MatrixBase. * the optimization of eval() for Matrix now consists in a partial specialization of ei_eval, which returns a reference type for Matrix. No overriding of eval() in Matrix anymore. Consequence: careful, ei_eval is no longer guaranteed to give a plain matrix type! For that, use ei_plain_matrix_type, or the PlainMatrixType typedef. * so lots of changes to adapt to that everywhere. Hope this doesn't break (too much) MSVC compilation. * add code examples for the new image() stuff. * lower a bit the precision for floats in the unit tests as we were already doing some workarounds in inverse.cpp and we got some failed tests.
* * call it beta2Gravatar Benoit Jacob2008-12-07
| | | | | * improvements in Matrix documentation * document copyCoeff and copyPacket even if it's hidden from doxygen
* * Much better, consistent error msgs when mixing different scalar types:Gravatar Benoit Jacob2008-12-03
| | | | | | | | | | | | | - 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
