56d00779db more product refactoring 2009-08-06 12:20:02 +02:00
Gael Guennebaud
7d607048a9 implement a ProductBase class and, as a proof of concept, update TriangularProduct 
and SelfAdjointMatrixProduct to take advantage of it => fewer LOC

f4112dcff3 The new trsm is working very very well (read very fast) for 
lower triangular matrix and row or col major lhs.
TODO: handle upper triangular and row major rhs cases

a81388fae9 Implement efficient sefladjoint product (aka SYRK) : C += alpha * U U^T 
It is currently available via SelfAdjointView::rankKupdate.
TODO: allows to write SelfAdjointView += u * u.adjoint()

d6627d540e * refactoring of the matrix product into multiple small kernels 
* started an efficient selfadjoint matrix * general matrix product
  based on the generic kernels ( => need a very little LOC)

32b08ac971 re-implement stableNorm using a homemade blocky and 
vectorization friendly algorithm (slow if no vectorization)

587029a612 started an implementation of BandMatrix: at least the read/write access 
to the main/sub/super diagonals seems to work well.

a2087cd7a3 Add an efficient rank2 update function (like the level2 blas xSYR2 routine). 
Note that it is already used in Tridiagonalization.

ec5c608aa3 Set of fixes and workaround to make sun studio more happy. 
Still remains the problem of alignment and vectorization.

1aea45335f * bybye Part, welcome TriangularView and SelfAdjointView. 
* move solveTriangular*() to TriangularView::solve*()
* move .llt() to SelfAdjointView
* add a high level wrapper to the efficient selfadjoint * vector product
* improve LLT so that we can specify which triangular part is meaningless
=> there are still many things to do (doc, cleaning, improve the matrix products, etc.)

6347b1db5b remove sentence "Eigen itself is part of the KDE project." 
it never made very precise sense. but now does it still make any?

8aa8854bbf fix SSE2 detection on win64, reported by 'kajala' 2009-05-04 12:13:37 +00:00
Benoit Jacob
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.

49fc1e3e84 add vectorization of sqrt for float 2009-03-27 14:41:46 +00:00
Gael Guennebaud
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
* rename reverse.cpp array_reverse.cpp

6a26506341 add ReturnByValue pseudo expression for in-place evaluation with a 
return-by-value API style (will soon use it for the transform products)

* add an efficient selfadjoint * vector implementation (= blas symv)
  perf are inbetween MKL and GOTO
  => the interface is still missing (have to be rethougth)

Kenneth Frank Riddile
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

8106d35408 Patch by Kenneth Riddile: disable MSVC warnings, reenable them outside 
of Eigen, and add a MSVC-friendly path in StaticAssert.

38b83b4157 * throw bad_alloc if exceptions are enabled, after patch by Kenneth Riddile

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.
* Some compilation fixes
