763f0a2434 use ei_aligned_malloc and ei_aligned_free also in WithAlignedOperatorNew, so this too should now work with MSVC. 2008-12-15 17:55:11 +00:00

beabf008b0 bugfix in DiagonalProduct: a "DiagonalProduct<SomeXpr>" expression 
is now evaluated as a "DiagonalProduct<Matrix<SomeXpr::Eval> >".
Note that currently this only happens in DiagonalProduct.

cb409914e0 * call it beta2 
* improvements in Matrix documentation
* document copyCoeff and copyPacket even if it's hidden from doxygen

09fd69d734 * add Transform explicit constructors taking translation/scaling/rotation 
* add Transform::operator= taking rotation.
  An old remnant was left commented out. Why was it disabled?
* slight optimization in operator= taking translation
* slight optimization (perhaps) in the new memory assertion

08e6b7ad80 Make deluxe assertion with deluxe error message with link to deluxe web page 
for this very nasty bug (unaligned member in dynamically allocated struct)
that our friends at Krita just encountered:

7e8ee5b527 hide internal stuff from doxygen by using #ifndef EIGEN_PARSED_BY_DOXYGEN. 
Sadly, \internal didn't hide internal stuff, it only hides the documentation!

bb33ec4ef3 * fix compile error when C++0x is enabled: static_assert() needs ; 
thanks to devurandom for reporting
* remove redundant ; in ei_internal_assert

faf942a947 Add a generic matrix to Euler-angles function. 
Perhaps the prototype of this function could be improved,

c1e2156d8a * Much better, consistent error msgs when mixing different scalar types: 
- in matrix-matrix product, static assert on the two scalar types to be the same.
- Similarly in CwiseBinaryOp. POTENTIALLY CONTROVERSIAL: we don't allow anymore binary
  ops to take two different scalar types. The functors that we defined take two args
  of the same type anyway; also we still allow the return type to be different.
  Again the reason is that different scalar types are incompatible with vectorization.
  Better have the user realize explicitly what mixing different numeric types costs him
  in terms of performance.
  See comment in CwiseBinaryOp constructor.
- This allowed to fix a little mistake in test/regression.cpp, mixing float and double
- Remove redundant semicolon (;) after static asserts

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.
