a96c849c20 Document enums in Constants.h (bug #248). 
To get the links to work, I also had to document the Eigen namespace.
Unfortunately, this means that the word Eigen is linked whenever it appears
in the docs.

85f9fab003 back out changeset efdf2e4056 
. It turns out that the SSE3 header is always included, even without any SSE enabled, so it was making us wrongly use SSE3 paths. Backing this out fixes msvc related crashes, at least bug #165.

fd400ffffb reverse order of testing for eigen2 support stages. Higher stages now have priority. So if your whole project builds with say stage 10, you can manually enable stage 20 for selected files. 2011-01-27 10:34:44 -05:00

7a7ca99a31 [mq]: Mingw32 fix 
intrin.h is not required nor supported by mingw32.  It is present (and supported) on mingw-w64 builds, even those for 32-bit systems, but here too it's not required on 32-bit systems.  So if we're on mingw, and it's 64-bit, then and only then is the intrin.h inclusion necessary.

0928c40f68 rename Coeffs.h -> DenseCoeffsBase.h 2010-05-08 16:02:13 -04:00
Benoit Jacob
bfdc1c4973 introduce DenseCoeffsBase: this is where the coeff / coeffRef / etc... methods go. 
Rationale: coeffRef() methods should only exist when we have DirectAccess. So a natural thing to do would have been to use enable_if, but since there are many methods it made more sense to do the "enable_if" for the whole group by introducing a new class. And that also that the benefit of not changing method prototypes.

112c550b4a Added initial NEON support, most tests pass however we had to use some hackish workarounds 
as gcc on ARM (both CodeSourcery 4.4.1 used and experimental 4.5) fail to
ensure proper alignment with __attribute__((aligned(16))). This has to be
fixed upstream to remove the workarounds.

7b0c4102fa * add a Make* expression type builder to allow the 
construction of generic expressions working
  for both dense and sparse matrix. A nicer solution
  would be to use CwiseBinaryOp for any kind of matrix.
  To this end we either need to change the overall design
  so that the base class(es) depends on the kind of matrix,
  or we could add a template parameter to each expression
  type (e.g., int Kind = ei_traits<MatrixType>::Kind)
  allowing to specialize each expression for each kind of matrix.

- make .lazy() remove the MayAliasBit only, and mark it as deprecated
- add a NoAlias pseudo expression, and MatrixBase::noalias() function
Todo:
- we have to decide whether += and -= assume no aliasing by default ?
- once we agree on the API: update the Sparse module and the unit tests respectively.

95bda5e6ab let the user disable alignment altogether by #defining EIGEN_DONT_ALIGN. 
Until now, the user had to edit the source code to do that.
Internally, add EIGEN_ALIGN that takes into account both EIGEN_DONT_ALIGN.and
EIGEN_ARCH_WANTS_ALIGNMENT. From now on, only EIGEN_ALIGN should be used to
test whether we want to align.

17860e578c add SSE2 versions of sin, cos, log, exp using code from Julien 
Pommier. They are for float only, and they return exactly the same
result as the standard versions in about 90% of the cases. Otherwise the max error
is below 1e-7. However, for very large values (>1e3) the accuracy of sin and cos
slighlty decrease. They are about 3 or 4 times faster than 4 calls to their respective
standard versions. So, is it ok to enable them by default in their respective functors ?

0be89a4796 big addons: 
* add Homogeneous expression for vector and set of vectors (aka matrix)
  => the next step will be to overload operator*
* add homogeneous normalization (again for vector and set of vectors)
* add a Replicate expression (with uni-directional replication
  facilities)
=> for all of them I'll add examples once we agree on the API
* fix gcc-4.4 warnings

f52a9e5315 * Added aligned_allocator for using 16-byte aligned types with STL containers. There is still a compile-time problem with STL containers that have a standard-conformant resize() method, but this should resolve the original user issue which was storing aligned objects in a std::map. 2009-01-09 00:55:53 +00:00

IoFormat OctaveFmt(4, AlignCols, ", ", ";\n", "", "", "[", "]");
   cout << mat.format(OctaveFmt);
  The first "4" is the precision.
  Documentation missing.

Gael Guennebaud
4fa40367e9 * Big change in Block and Map: 
- added a MapBase base xpr on top of which Map and the specialization
    of Block are implemented
  - MapBase forces both aligned loads (and aligned stores, see below) in expressions
    such as "x.block(...) += other_expr"
* Significant vectorization improvement:
 - added a AlignedBit flag meaning the first coeff/packet is aligned,
   this allows to not generate extra code to deal with the first unaligned part
 - removed all unaligned stores when no unrolling
 - removed unaligned loads in Sum when the input as the DirectAccessBit flag
* Some code simplification in CacheFriendly product
* Some minor documentation improvements
