25f8adfa6c * Fix bug #79: ei_alignmentOffset was assuming that ptr is multiple of 
sizeof(Scalar), and that assumption breaks with double on linux x86-32.
* Rename ei_alignmentOffset to ei_first_aligned
* Rewrite its documentation and part of its body
* The variant taking a MatrixBase doesn't need a separate size argument.

791bac25f2 fix #75, and add a basic unit test for Hessenberg 
(it was indirectly tested by the eigenvalue decomposition)

945cbc3bc6 Add test for issue #75 (Hessenberg of 1x1 matrix). 
Also remove an superfluous #include in matrixExponential test.

6db6774c46 * fix aliasing checks when the lhs is also transposed. At the same time, 
significantly simplify the code of these checks while extending them
  to catch much more expressions!
* move the enabling/disabling of vectorized sin/cos to the architecture traits

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.

d088ee35f6 Added to possibility to compile unit tests at maximum warning level. 
Silenced (amongst others) many conversion related warnings.

d2e44f2636 * 4x4 inverse: revert to cofactors method 
* inverse tests: use createRandomMatrixOfRank, use more strict precision
* tests: createRandomMatrixOfRank: support 1x1 matrices
* determinant: nest the xpr
* Minor: add comment

de25059502 * Remove test_ prefix in tests

3e73f6036c * HouseholderSequence: 
* be aware of number of actual householder vectors
    (optimization in non-full-rank case, no behavior change)
  * fix applyThisOnTheRight, it was using k instead of actual_k
* QR: rename matrixQ() to householderQ() where applicable

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

6cbf662f14 * don't laugh, but these bugs took me forever to fix. 
* expand unit tests to make sure to catch them: they nearly escaped the existing tests as these memory violations were highly dependent on the numbers of rows and cols.

6680fa42ee * add Map<Quaternion> test based on Map from test/map.cpp 
* replace implicit constructor AngleAxis(QuaternionBase&) by an explicit one, it seems ambiguous for the compiler
* remove explicit constructor with conversion type quaternion(Quaternion&): conflict between constructor.
* modify EIGEN_INHERIT_ASSIGNEMENT_OPERATORS to suit Quaternion class

fc492b6264 add mctestr script. In your build directory, just do: 
./mctestr ^qr 5
and it will build all tests matching ^qr with 5 jobs and then do `ctest -R ^qr`

bc18ba7e49 * add maketests script. It is like make but takes a regexp allowing to build selected targets. Next step will be a "mctestr" script doing that and then calling ctest -R. 
* in runtest.sh, don't override the default number of repeats. If one thinks the default should be changed, let's change it at the source.
