fe81b3f651 Add the possibility to control the storage mode of scalar value (by value or reference)
in order to avoid unecessary copies when using complex scalar types (e.g., a AutoDiffScalar)

3979f6d8aa Let's try to stick to the original code, thus activate the fix of #62 only for 64 bit builds. 2009-11-04 15:49:22 +01:00

48261fc773 * default MatrixBase ctor: make it protected, make it a static assert, only do the check when debugging eigen to avoid slowing down compilation for everybody (this check is paranoiac, it's very seldom useful)
* add private MatrixBase ctors to catch cases when the user tries to construct MatrixBase objects directly

2840ac7e94 big huge changes, so i dont remember everything.
* renaming, e.g. LU ---> FullPivLU
* split tests framework: more robust, e.g. dont generate empty tests if a number is skipped
* make all remaining tests use that splitting, as needed.
* Fix 4x4 inversion (see stable branch)
* Transform::inverse() and geo_transform test : adapt to new inverse() API, it was also trying to instantiate inverse() for 3x4 matrices.
* CMakeLists: more robust regexp to parse the version number
* misc fixes in unit tests

ec02388a5d big rewrite in Inverse.h
in particular, the API is essentially finalized and the 4x4 case is fixed to be numerically stable.

a382963b04 * extend Map to allow the user to specify whether the mapped data
is aligned or not. This is done using the Aligned constant:
  Map<MatrixType,Aligned>::Map(data);
* rename ForceAligned to EnforceAlignedAccess, and update its doc,
  and emphasize this is mainly an internal stuff.

c3180b7ffb MatrixBase:
* support resize() to same size (nop). The case of FFT was another case where that make one's life far easier.
   hope that's ok with you Gael. but indeed, i don't use it in the ReturnByValue stuff.

FFT:
 * Support MatrixBase (well, in the case with direct memory access such as Map)
 * adapt unit test

9a700c2974 * LU unit test: finally test fixed sizes
* ReturnByValue: after all don't eval to temporary for generic MatrixBase impl

8332c232db big huge changes in LU!
* continue the decomposition until a pivot is exactly zero;
  don't try to compute the rank in the decomposition itself.
* Instead, methods such as rank() use a new internal parameter
  called 'threshold' to determine which pivots are to be
  considered nonzero.
* The threshold is by default determined by defaultThreshold()
  but the user can override that by calling useThreshold(value).
* In solve/kernel/image, don't assume that the diagonal of U
  is sorted in decreasing order, because that's only approximately
  true. Additional work was needed to extract the right pivots.

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.
* Extend AutoDiffScalar to work with sparse vector expression
  for the derivatives.

904f35d194 discard vectorization in matrix-vector product when data is not even

bb1cc0d092 after all we're not aligning to 8byte boundary
keep most of the changes though as they make the code more extensible
2009-10-05 10:55:42 -04:00

d41577819b we were already aligning to 16 byte boundary fixed-size objects that are multiple of 16 bytes;
now we also align to 8byte boundary fixed-size objects that are multiple of 8 bytes.
That's only useful for now for double, not e.g. for Vector2f, but that didn't seem to hurt. Am I missing something? Do you prefer that we don't align Vector2f at all?
Also, improvements in test_unalignedassert.

fa65b09661 add outerproduct coeff(int,int) method.
This is needed to make this expression work:
(vec1*vec2.transpose())*vec3
Gael, no objection? Seems to make sense as that's fast.

765600458b * bump to 2.90.0 now that it's agreed that we're doing eigen3
---> question: do we change the prefix eigen2/ to eigen3/ now?
       no, better wait until we've also changed the repository name
* more message improvements: "Install Eigen" was unclear as it left
  out other things like the BLAS library

924b55e9a9 when copying a ReturnByValue into a MatrixBase, first eval it to a PlainMatrixType.
This allows to limit the number of instantiations of the big template method evalTo.
Also allows to get rid of the dummy MatrixBase::resize().
See "TODO" comment.

e82ab8a5dd move also inverse() to ReturnByValue, by doing a solve on NestByValue<Identity>.
also: adding resize() to MatrixBase was really needed ;)
