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.
|

|
|
|
|

* CholeskyWithoutSqrt with 1x1 matrices
* .part<Diagonal>()
Updated unit tests to handle these cases

mat.cwise() < 2
instead of:
mat.cwise() < MatrixType::Constant(mat.rows(), mat.cols(), 2)
|
| |
|
|
|
|

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")

Anyway: LinearVectorization+CompleteUnrolling actually uses the InnerVectorization
unrollers, so these two cases could be merged to a single one...

* 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"...

Block specialization for sparse matrices.
InnerIterators for Blocks and fixes in CoreIterators.

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.

EIGEN_SOURCE_DIR for that use, guaranteed to point to eigen2/ directory.

* Fix compilations with gcc 3.4, ICC and doxygen
* Fix krazy directives (hopefully)

API update in Regression...

and more code factorization based on RotationBase.
Added notes about the main aim of the Translation and Scaling classes.
|
| |
|
|
|
|
|
|
| |
This allow code factorization and generic template specialization
of functions
* added any_rotation * {Translation,Scaling,Transform} products methods
* rewrite of the actually broken ToRoationMatrix helper class to
a global ei_toRotationMatrix function.
|
| | |
|
| |
|
|
|
| |
* apply the same principle to extractRotation and fix it to
extract a rotation corresponding to a positive scaling
|

transformation is:
NonAffine, Affine (default), contains NoShear, contains NoScaling
that allows significant speed improvements. If you like it, this concept could be applied to
Transform::extractRotation (or to a more advanced decomposition function) and to Hyperplane::transformed()
and maybe to some other places... e.g., I think a Transform::normalMatrix() function would not harm and
warn user that the transformation of normals is not that trivial (I saw this mistake much too often)

* handling Quaternion, AngleAxis and Rotation2D, 2 options here:
1- make all of them inheriting a common base class Rotation such that we can
have a single version of operator* for all the rotation type (they all get converted to a matrix)
2- write a version for all type (so 3 rotations types * 3 for Transform,Translation and Scaling)
* real documentation

plus some hacks to compile the examples from doxygen...
Hopefully, api.kde.org/eigen2 will be beautiful by tomorrow....
|

|

- the coefficients are stored in a single vector
- added transformation methods
- removed Line* typedef since in 2D this is really an hyperplane
and not really a line...
- HyperPlane => Hyperplane

with its respective unit-test.
Feel free to discuss the API on the ML.
* Some bugfix in unitOrthogonal found by the hyperplane unit test.
|

but I no hope, that would be too simple !
* added Rotation2D typedefs
* remove CoreDeclarations header file
|

to compile (duplicate symbols).
|
| |
|
|
|
|
|

* show svn revision number if available
* fix warnings about unused argc/argv
Gael: I just saw your latest docs, it's completely awesome.

* keep going on the doc: added a short geometry tutorial
|
| |
|
|
|
| |
* clean ugly doxygen inheritence of expressions
* keep improving the documentation... slowly !
|
| | |
|

and various cleaning in Altivec code. Altivec vectorization have been re-enabled
in CoreDeclaration
* added copy constructors in non empty functors because I observed weird behavior with
std::complex<>
