* Sparse module: refactoring of the cholesky factorization,Gravatar Gael Guennebaud2008-10-05

|
* Sparse module:Gravatar Gael Guennebaud2008-10-04
| | | | | | | | | | * several fixes (transpose, matrix product, etc...) * Added a basic cholesky factorization * Added a low level hybrid dense/sparse vector class to help writing code involving intensive read/write in a fixed vector. It is currently used to implement the matrix product itself as well as in the Cholesky factorization.
* add EigenSolver::eigenvectors() method for non symmetric matrices.Gravatar Gael Guennebaud2008-10-03
| | | | | | However, for matrices larger than 5, it seems there is constantly a quite large error for a very few coefficients. I don't what's going on, but that's certainely not due to numerical issues only. (also note that the test with the pseudo eigenvectors fails the same way)
* Fixes in Eigensolver:Gravatar Gael Guennebaud2008-10-01
| | | | | | | | * eigenvectors => pseudoEigenvectors * added pseudoEigenvalueMatrix * clear the documentation * added respective unit test Still missing: a proper eigenvectors() function.

* fix doc compilationGravatar Gael Guennebaud2008-09-13
|
* * Quaternion: added dot product and angularDistance functions. The latter isGravatar Gael Guennebaud2008-09-11
| | | | | | based on the former. * opengl_demo: makes IcoSphere better (vertices are instanciated only once) and removed the generation of a big geometry for the fancy spheres...
* opengl demo, now working:Gravatar Gael Guennebaud2008-09-09
| | | | | | - quaternion vs euler angles interpolation (though the Euler angle version looks a bit too bad) - navigation using either a mapping from 2D screen coordinates to 3D points on a sphere or the standard approach mapping mouse displacements as rotations around camera's axes.
* various stuff in opengl demos such as a better model,Gravatar Gael Guennebaud2008-09-09
| | | | | stable trackball for the fly navigation mode, and started to put some GUI elements...

| | | | stable as LU with full pivoting)
* fix warningGravatar Benoit Jacob2008-09-04
|
* * Extend a bit ParametrizedLine and move it to a separate file,Gravatar Gael Guennebaud2008-09-03
| | | | | | 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.
* Fix bugs reported by Timothy Hunter:Gravatar Gael Guennebaud2008-09-03
| | | | | | * CholeskyWithoutSqrt with 1x1 matrices * .part<Diagonal>() Updated unit tests to handle these cases
* Add coeff-wise comparisons to scalar operators. You can now write:Gravatar Gael Guennebaud2008-09-03
| | | | | | mat.cwise() < 2 instead of: mat.cwise() < MatrixType::Constant(mat.rows(), mat.cols(), 2)
* Add a Select expression in the Array module which mimics a coeff-wise ?: ↵Gravatar Gael Guennebaud2008-09-03
| | | | | | | | operator. Example: mat = (mat.cwise().abs().cwise() < Ones()).select(0,mat); replaces all small values by 0. (the scalar version is "s = abs(s)<1 ? 0 : s")
* trivial compilation fix in SVDGravatar Gael Guennebaud2008-09-03
|
* Bugfix regarding alignent in Assign.h (updated map unit test to detect this bug)Gravatar Gael Guennebaud2008-09-03
| | | | | Anyway: LinearVectorization+CompleteUnrolling actually uses the InnerVectorization unrollers, so these two cases could be merged to a single one...
* compilation fixes with MSVCGravatar Gael Guennebaud2008-09-03

* not yetGravatar Gael Guennebaud2008-09-03
|
* Solve a big issue with data alignment and dynamic allocation:Gravatar Gael Guennebaud2008-09-03
| | | | | | | | | | | | | | | | * 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"...

* Extended sparse unit-test: nested blocks and InnerIterators.Gravatar Daniel Gomez Ferro2008-09-02
| | | | | Block specialization for sparse matrices. InnerIterators for Blocks and fixes in CoreIterators.
* if EIGEN_NICE_RANDOM is defined, the random functions will return numbers withGravatar Benoit Jacob2008-09-01
| | | | | | few bits left of the comma and for floating-point types will never return zero. This replaces the custom functions in test/main.h, so one does not anymore need to think about that when writing tests.
* remove the conceptualy broken "NoShear" transformation traits,Gravatar Gael Guennebaud2008-09-01
| | | | and rename NonAfine => Projective, GenericAffine => Affine, NoScaling => Isometry
* QTransform conversion and docGravatar Gael Guennebaud2008-09-01

* update of the geometry tutorialGravatar Gael Guennebaud2008-08-31
