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.

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

6c1b91678b kill ei_add_test_multi. Now the macro ei_add_test does all that automatically, by parsing the source file. No risk anymore to specify the wrong number of tests! Also, introduce CALL_SUBTESTX for X=1..10 that allows to port existing code much quicker. And port already the product* and eigensolver* files. 2009-10-19 14:40:35 -04:00

580672ea43 Add new default option EIGEN_SPLIT_LARGE_TESTS and cmake macro ei_add_test_multi. 
When enabled, large tests are split into smaller executables.
This needs minimal changes in the unit tests.
Updated the LU test to use it.

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.

Removed the make usage message for MSVC_IDE.

904f35d194 discard vectorization in matrix-vector product when data is not even 
aligned on the scalar type size (e.g., for double on 32 bits system without -malign-double)

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.

b78b2ede5f finally, the right fix: set CTEST_BUILD_TARGET. 
So this is the come-back of btest target, and the default target is empty again.
 2009-10-04 20:27:44 -04:00
Benoit Jacob
a1d9b76dd5 add debug targets like debug_qr to build a specific test with debug info 
remove the btest target, instead just do "make" since anyway we have to let "make" build the tests

eeabd18afc Fix compilation of HouseholderQR and ColPivotingHouseholderQR for non-square fixed-size matrices. 
For Colpiv that was just changing MatrixQType to MatrixType in the instantiation of HouseholderSequence.
For HouseholderQR I also re-ported the solve method from Colpiv as there were multiple issues.

* remove EIGEN_BUILD_TESTS and siblings
* add summary at the end of cmake run, hopefully not too verbose
* fix build of quaternion demo
* kill remnants of old binary library option

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

4f9e270343 * make LU::kernel() and LU::image() also use ReturnByValue 
* make them return zero vector in the degenerate case, instead of asserting
  (let's stick to the principle that we only assert on memory errors)

c1c780a94f * ReturnByValue: 
-- simpplify by removing the 2nd template parameter
  -- rename Functor to Derived, as now it's a usual CRTP
* Homogeneous:
  -- in products, honor the Max sizes etc.

46be9c9ac1 * fix super nasty bug: vector.maxCoeff(&index) didn't work when 'vector' 
was a row-vector. Fixed by splitting the vector version from the matrix version.
* add unit test, the visitors weren't covered by any test!!
