5cb779e5e1 * introduce ei_alignmentOffset(MatrixBase&,Integer) 
couldnt put it in Memory.h as it needs the definition of MatrixBase
* make Redux use it

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

3ea1f97f69 Suppressed the warning for missing assignment generators (forgot that in the last submission). 
Commented Quake3's fast inverser sqrt in SSE's MathFunction header.

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.

d5f3b2dc94 change the Arch constants: const int ---> enum, more explicit names, and use 
of a namespace instead of Prefix_Name.

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

8bfa354ee3 Documentation clean up. 
* remove non-existant reference to CwiseAll
* define \householder_module (used in HouseholderSequence.h)
* update I01_TopicLazyEvaluation.dox - Product is now called GeneralProduct
* remove reference to list of examples which was deleted ages ago
* rename PartialLU_solve.cpp snippet to PartialPivLU_solve.cpp

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

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.

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

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.

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.
