46fe7a3d9e if EIGEN_NICE_RANDOM is defined, the random functions will return numbers with
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.

49ff9b204c remove the conceptualy broken "NoShear" transformation traits,
and rename NonAfine => Projective, GenericAffine => Affine, NoScaling => Isometry

5c8c09e021 add uniform scale/prescale functions in Tranform 2008-08-30 23:10:46 +00:00

6ba991aa3a * added a RotationBase class following the CRT pattern
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.

f1e6c56b77 * rename TranformationKnowledge to TransformTraits
* apply the same principle to extractRotation and fix it to
  extract a rotation corresponding to a positive scaling

236b7a545d update Transform::inverse() to take an optional argument stating whether the 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)

9e7a9cde14 Add Scaling and Translation class as discussed on ML, still missing:
* 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

6d841512c7 some hyperplane changes:
- 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

5ac883b10a Fix a bug discovered in Avogadro: the AngleAxis*Matrix and the newer
AngleAxis*Vector products were wrong because they returned the product
_expression_
   toRotationMatrix()*other;
and toRotationMatrix() died before that expression would be later
evaluated. Here it would not have been practical to NestByValue as this
is a whole matrix. So, let them simply evaluate and return the result by
value.

The geometry.cpp unit-test only checked for compatibility between
various rotations, it didn't check the correctness of the rotations
themselves. That's why this bug escaped us. So, this commit checks that
the rotations produced by AngleAxis have all the expected properties.
Since the compatibility with the other rotations is already checked,
this should validate them as well.

251ecc0ab9 Rename someOrthogonal to unitOrthogonal. Fix a bug in it, with dyn-size vectors of size <=3.
Update doc and test to reflect that it always returns a unit vector.

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...)

f0394edfa7 * bugfix in SolveTriangular found by Timothy Hunter (did not compiled for very small fixed size matrices)
* bugfix in Dot unroller
* added special random generator for the unit tests and reduced the tolerance threshold by an order of magnitude
  this fixes issues with sum.cpp but other tests still failed sometimes, this have to be carefully checked...

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.

 - handles non square matrices of size MxN with M>=N
 - does not work for complex matrices

baf0cffedd *add operator()(int) for vectors, synonymous to operator[](int).
I don't see any reason not to allow it, it doesn't add much code, and
 it makes porting from eigen1 easier.
*expand tests/basicstuff to first test coefficient access methods

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.

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.

05ad083467 Added MatrixBase::Unit*() static function to easily create unit/basis vectors.
Removed EulerAngles, addes typdefs for Quaternion and AngleAxis,
and added automatic conversions from Quaternion/AngleAxis to Matrix3 such that:
 Matrix3f m = AngleAxisf(0.2,Vector3f::UnitX) * AngleAxisf(0.2,Vector3f::UnitY);
just works.

62ec1dd616 * big rework of Inverse.h:
- remove all invertibility checking, will be redundant with LU
  - general case: adapt to matrix storage order for better perf
  - size 4 case: handle corner cases without falling back to gen case.
  - rationalize with selectors instead of compile time if
  - add C-style computeInverse()
* update inverse test.
* in snippets, default cout precision to 3 decimal places
* add some cmake module from kdelibs to support btl with cmake 2.4

b7bd1b3446 Add a *very efficient* evaluation path for both col-major matrix * vector
and vector * row-major products. Currently, it is enabled only is the matrix
has DirectAccessBit flag and the product is "large enough".
