e5b8a59cfa Add smart cast functions and ctor with scalar conversion (explicit) 
to all classes of the Geometry module. By smart I mean that if current
type == new type, then it returns a const reference to *this => zero overhead

8ea8b481de As discussed on ML: 
* remove the automatic resizing feature of operator =
 * add function Matrix::set() to be used when the previous
   behavior is wanted
 * the default constructor of dynamic-size matrices now
   creates a "null" matrix (data=0, rows = cols = 0)
   instead of a 1x1 matrix
 * fix UnixX typos ;)

765219aa51 Big API change in Cholesky module: 
* rename Cholesky to LLT
 * rename CholeskyWithoutSquareRoot to LDLT
 * rename MatrixBase::cholesky() to llt()
 * rename MatrixBase::choleskyNoSqrt() to ldlt()
 * make {LLT,LDLT}::solve() API consistent with other modules

Note that we are going to keep a source compatibility untill the next beta release.
E.g., the "old" Cholesky* classes, etc are still available for some time.
To be clear, Eigen beta2 should be (hopefully) source compatible with beta1,
and so beta2 will contain all the deprecated API of beta1. Those features marked
as deprecated will be removed in beta3 (or in the final 2.0 if there is no beta 3 !).

Also includes various updated in sparse Cholesky.

     temporary before the computations.
Add solveInPlace in Cholesky*

e14aa8c8aa Add coeff-wise comparisons to scalar operators. You can now write: 
mat.cwise() < 2
instead of:
   mat.cwise() < MatrixType::Constant(mat.rows(), mat.cols(), 2)
 2008-09-03 17:56:06 +00:00
Gael Guennebaud
59dc1da5bf Add a Select expression in the Array module which mimics a coeff-wise ?: 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")

3bbd1b3114 Bugfix regarding alignent in Assign.h (updated map unit test to detect this bug) 
Anyway: LinearVectorization+CompleteUnrolling actually uses the InnerVectorization
unrollers, so these two cases could be merged to a single one...

f52d119b9c Solve a big issue with data alignment and dynamic allocation: 
* 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"...

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.

9c450a52a2 Split Rotation.h to Rotation2D.h and RotationBase.h, 
and more code factorization based on RotationBase.
Added notes about the main aim of the Translation and Scaling classes.

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

3ced3f91c2 * temporarily remove doxygen customization, we'll see if that fix api.kde.org 
but I no hope, that would be too simple !
