e2bd8623f8 Solve the issue found by Timothy in solveTriangular: 
=> row-major rhs are now evaluated to a column-major
     temporary before the computations.
Add solveInPlace in Cholesky*

b46c327133 Clear up the docs some. I'd also suggest making Dynamic the default template parameter for matrices. 2008-10-11 08:43:18 +00:00

c29c7b0ea9 Fix bugs reported by Timothy Hunter: 
* CholeskyWithoutSqrt with 1x1 matrices
 * .part<Diagonal>()
Updated unit tests to handle these cases

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...

75649551c2 compilation fixes with MSVC 2008-09-03 11:26:19 +00:00
Gael Guennebaud
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.

Gael Guennebaud
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 !

8f9d30cb20 * patch from Konstantinos Margaritis: bugfix in Altivec version of ei_pdiv 
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<>

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...)
* added a CustomizeEigen.dox page
* added a TOC to QuickStartGuide.dox

f2f48b6560 * remove LargeBit and related stuff 
* replaced the Flags template parameter of Matrix by StorageOrder
  and move it back to the 4th position such that we don't have to
  worry about the two Max* template parameters
* extended EIGEN_USING_MATRIX_TYPEDEFS with the ei_* math functions

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...

0998c51d1f - remove the ASM macro as in fact Gael had been removing all the remaining 
asm("...") from the code while fixing MSVC compat (so your changes crossed
  one another).
- move the pragma warning to CoreDeclarations, it's the right place to do early
  platform checks.
