Benoit Jacob
d02eccf584 add SSE path for Matrix4f inverse, taken from Intel except that we do a kosher 
division instead of RCPPS-followed-by-Newton-Raphson. The rationale for that is
that elsewhere in Eigen we dont allow ourselves this approximation (which throws
2 bits of mantissa), so there's no reason we should allow it here.

68117c267c ColPivQR: now the unit tests even succeeds: 
* with random matrices multiplied by 1e+8 (i.e. fixed wrong absolute fuzzy compare)
* with 10,000 repetitions (i.e. the fuzzy compare is really clever)
and when it occasionnally fails, less than once in 10,000 repeats, it is only on the exact rank computation.
 2009-12-01 13:51:35 -05:00
Benoit Jacob
95d88e1327 Big reworking of ColPivQR and its unit test, which now passes even with thousands of repetitions and correctly tests matrices of all sizes. Several surprises along the way: for example, a major cause of trouble was the optimized "table of column squared norms" where the accumulation of imprecision was a serious issue; another surprise is that tests like "x!=0" before dividing by x really benefit from being replaced by fuzzy tests, as i hit real cases where i got wrong results in 1/epsilon. 2009-12-01 13:26:29 -05:00

eb8f450071 Hey, finally the copyCoeff stuff is not only used to implement swap anymore :) 
Add an internal pseudo expression allowing to optimize operators like +=, *= using
the copyCoeff stuff.
This allows to easily enforce aligned load for the destination matrix everywhere.

b0baf43114 Eigen/CMakeLists.txt: remove parens from if. 
Only CMake 2.6.3 and later recognize this syntax, and at the moment we
require 2.6.2. CMake uses the right precendence, per its man page, so the
parentheses are not necessary.

40865fa28c fix bugs, old and new: 
* old bug: in CwiseBinaryOp: only set the LinearAccessBit if both sides have the same storage order.
* new bug: in Assign.h, only consider linear traversal if both sides have the same storage order.
 2009-11-18 17:20:39 -05:00
Benoit Jacob
11fa2ae2c6 temporarily disable linear traversal. 
Actually I don't think it's buggy. But it probably triggers existing bugs, I suspect that
some xprs have LinearAccessBit and shouldn't have it.
Also this fixes the "bugs" with JacobiSVD ---> now it works again

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

6219f9acfa * rename new Quat class to Quaternion, remove existing Quaternion 
* add Copyright line for Mathieu
* cast() was broken (compile errors) and needed anyway to be in QuaternionBase
* it's VectorBlock<T,3>, don't pass additional parameter 1, it has different meaning!!
* make it compile with GCC (put 'typename' at the right location)

new classes :
* QuaternionBase
* Map<Quaternion>

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

13f31b8daf * make PartialLU avoid to generate inf/nan when given a singular matrix 
(result undefined, but at least it won't take forever on intel 387)
* add lots of comments, especially to LU.h
* fix stuff I had broken in Inverse.h
* split inverse test

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

47eeb40380 remove the m_originalMatrix member. Instead, image() now takes the original matrix as parameter. It was the only method to use it anyway. Introduce m_isInitialized. 2009-10-18 15:21:19 -04:00

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.
