0c89475317 unit tests for == / != operators 2010-01-17 23:57:59 +01:00

bfe6fdde24 allow to multiply a householder sequence and a matrix when one is real and one is complex. 
This is especially important as in bidiagonalization, the band matrix is real.

f1d1756cdd Introduce third template parameter to HouseholderSequence: int Side. 
When it's OnTheRight, we read householder vectors as rows above the diagonal.
With unit test. The use case will be bidiagonalization.

24a09ceae8 * Fix a bug in HouseholderQR with mixed fixed/dynamic size: must use EIGEN_SIZE_MIN instead of EIGEN_ENUM_MIN, and there are many other occurences throughout Eigen! 
* HouseholderSequence:
  - add shift parameter
  - add essentialVector() method to start abstracting the direction
  - add unit test in householder.cpp

ef0ed5b271 test/triangular.cpp: isUpper() --> isUpperTriangular() 
Necessary to get the test to compile after c5d7c9f0de
.
I'm assuming that isUpperTriangular() is the name we want; the alternative
is to change Eigen/src/Core/{MatrixBase,TriangularMatrix}.h

82ec250a0f make applyHouseholderOnTheRight take a row vector, not a column vector: 
this is how it's used in practice.

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.

significantly simplify the code of these checks while extending them

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.

d2e44f2636 * 4x4 inverse: revert to cofactors method 
* inverse tests: use createRandomMatrixOfRank, use more strict precision
* tests: createRandomMatrixOfRank: support 1x1 matrices

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
