191d5275a7 modernize HouseholderQR too, uniformize all that stuff, update tests 2009-08-24 13:46:14 -04:00
Gael Guennebaud
ff0f005d4c change the make householder algorithm so that the remaining coefficient 
is real, and make Tridiagonalization use it

737bed19c1 make HouseholderQR uses the Householder module 2009-08-16 19:22:15 +02:00

e093b43b2c * rename QR to HouseholderQR because really that impacts the API, not just the impl. 
* rename qr() to householderQr(), for same reason.
* clarify that it's non-pivoting, non-rank-revealing, so remove all the rank API, make solve() be void instead of bool, update the docs/test, etc.
* fix warning in SVD

6347b1db5b remove sentence "Eigen itself is part of the KDE project." 
it never made very precise sense. but now does it still make any?

5c5789cf0f QR and SVD decomposition interface unification. 
Added default ctor and public compute method as
well as safe-guards against uninitialized usage.
Added unit tests for the safe-guards.

6358c12998 * introduced method createRandomMatrixOfRank (R = U*D*V where U,V unitary, D r-by-c diag. with rank non-zero values) 
* switched lu/qr tests to be using createRandomMatrixOfRank
* removed unused methods doSomeRankPreservingOperations
* removed NOTE about doSomeRankPreservingOperations

9b256d997e various minor updates of some unit tests 2009-05-11 11:09:41 +00:00

95db32fcdc setup the unsupported directory structure. 
The unsupported module documentation is automatically generated in:
  build/doc/unsupported/
with bidirectional cross references.
I leave a class Foo in AdolcForward module to illustrate the
cross-reference behavior. I will remove it in the next commit.

0f15a8d829 QR: add isInjective(), isSurjective(), 
mark isFullRank() deprecated,
    add solve() (mix of Keir's patch and LU::solve())
=> there is big problem with complex which are not working

c10f069b6b * Merge Extract and Part to the Part expression. 
Renamed "MatrixBase::extract() const" to "MatrixBase::part() const"
* Renamed static functions identity, zero, ones, random with an upper case
  first letter: Identity, Zero, Ones and Random.

e3fac69f19 Added a Hessenberg decomposition class for both real and complex matrices. 
This is the first step towards a non-selfadjoint eigen solver.
Notes:
 - We might consider merging Tridiagonalization and Hessenberg toghether ?
 - Or we could factorize some code into a Householder class (could also be shared with QR)

559233c73e * fix the QR module to use extract/part instead of the previous triangular stuff 
* added qr and eigensolver tests
* fix a compilation warning in Matrix copy constructor
