* allow to multiply a householder sequence and a matrix when one is real and ↵Gravatar Benoit Jacob2010-01-15
| | | | | | one is complex. This is especially important as in bidiagonalization, the band matrix is real.
* New UpperBidiagonalization classGravatar Benoit Jacob2010-01-14

* Introduce third template parameter to HouseholderSequence: int Side.Gravatar Benoit Jacob2010-01-14
| | | | | When it's OnTheRight, we read householder vectors as rows above the diagonal. With unit test. The use case will be bidiagonalization.
* * Fix a bug in HouseholderQR with mixed fixed/dynamic size: must use ↵Gravatar Benoit Jacob2010-01-11
| | | | | | | | | 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
* Fixed conservativeResize.Gravatar Hauke Heibel2010-01-11
| | | | | Fixed multiple overloads for operator=. Removed debug output.
* test/triangular.cpp: isUpper() --> isUpperTriangular()Gravatar Jitse Niesen2010-01-08
| | | | | | | Necessary to get the test to compile after c5d7c9f0def693e77797e6e43cb1fd2e7f8ae2fd . I'm assuming that isUpperTriangular() is the name we want; the alternative is to change Eigen/src/Core/{MatrixBase,TriangularMatrix}.h

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.
