2a3a6fe45e Experiment the ET refactoring on Transpose for Dense and Sparse storages. 
All tests work fine.

955cd7f884 * add PermutationMatrix 
* DiagonalMatrix:
   - add MaxSizeAtCompileTime parameter
   - DiagonalOnTheLeft ---> OnTheLeft
   - fix bug in DiagonalMatrix::setIdentity()

a440385b41 *adapt Householder to the convention that we now favor refs over ptrs for output. Keep "workspace" as pointer because it is an array (which is now more obvious). 
*rename makeHouseholderSequence to householderSequence, because that's what it returns.

48261fc773 * default MatrixBase ctor: make it protected, make it a static assert, only do the check when debugging eigen to avoid slowing down compilation for everybody (this check is paranoiac, it's very seldom useful) 
* add private MatrixBase ctors to catch cases when the user tries to construct MatrixBase objects directly

2840ac7e94 big huge changes, so i dont remember everything. 
* renaming, e.g. LU ---> FullPivLU
* split tests framework: more robust, e.g. dont generate empty tests if a number is skipped
* make all remaining tests use that splitting, as needed.
* Fix 4x4 inversion (see stable branch)
* Transform::inverse() and geo_transform test : adapt to new inverse() API, it was also trying to instantiate inverse() for 3x4 matrices.
* CMakeLists: more robust regexp to parse the version number
* misc fixes in unit tests

44cdbaba4d * make inverse() do a ReturnByValue 
* add computeInverseWithCheck
* doc improvements
* update test
 2009-10-26 14:16:50 -04:00
Benoit Jacob
ec02388a5d big rewrite in Inverse.h 
in particular, the API is essentially finalized and the 4x4 case is fixed to be numerically stable.

c3180b7ffb MatrixBase: 
* support resize() to same size (nop). The case of FFT was another case where that make one's life far easier.
   hope that's ok with you Gael. but indeed, i don't use it in the ReturnByValue stuff.

FFT:
 * Support MatrixBase (well, in the case with direct memory access such as Map)
 * adapt unit test

80ede36b24 allow arbitrary resulttype, fixes Xuewen's issue, and this stuff is going to get deeply refactored soon anyway. 2009-10-06 09:26:28 -04:00
Benoit Jacob
924b55e9a9 when copying a ReturnByValue into a MatrixBase, first eval it to a PlainMatrixType. 
This allows to limit the number of instantiations of the big template method evalTo.
Also allows to get rid of the dummy MatrixBase::resize().
See "TODO" comment.

e82ab8a5dd move also inverse() to ReturnByValue, by doing a solve on NestByValue<Identity>. 
also: adding resize() to MatrixBase was really needed ;)

176c26feb5 allow to do xpr = solve(b) etc... just by adding a dummy MatrixBase::resize() 2009-09-22 01:41:09 -04:00

c1c780a94f * ReturnByValue: 
-- simpplify by removing the 2nd template parameter
  -- rename Functor to Derived, as now it's a usual CRTP
* Homogeneous:
  -- in products, honor the Max sizes etc.

c6822d6723 Added EIGEN_REF_TO_TEMPORARY define for rvalue support.

49dd5d7847 * add a HouseholderSequence class (not good enough yet for Triadiagonalization and HessenbergDecomposition) 
* rework a bit AnyMatrixBase, and mobe it to a separate file

46be9c9ac1 * fix super nasty bug: vector.maxCoeff(&index) didn't work when 'vector' 
was a row-vector. Fixed by splitting the vector version from the matrix version.
* add unit test, the visitors weren't covered by any test!!

64095b6610 Changed the AnyMatrixBase / ei_special_scalar_op inheritance order as proposed by Gael.

b0aa2520f1 * add real scalar * complex matrix, real matrix * complex scalar, 
and complex scalar * real matrix overloads

b83654b5d0 * rename JacobiRotation => PlanarRotation

8392373d96 add a JacobiRotation class wrapping the cosine-sine pair with 
some convenient features (transpose, adjoint, product)

6e4e94ff32 * JacobiSVD: 
- support complex numbers
 - big rewrite of the 2x2 kernel, much more robust
* Jacobi:
 - fix weirdness in initial design, e.g. applyJacobiOnTheRight actually did the inverse transformation
 - fully support complex numbers
 - fix logic to decide whether to vectorize
 - remove several clumsy methods

fix for complex numbers

239ada95b7 add overloads of lazyAssign to detect common aliasing issue with 
transpose and adjoint
 2009-08-15 22:19:29 +02:00
Gael Guennebaud
50c703f0c7 As proposed on the list: 
- rename EvalBeforeAssignBit to MayAliasBit
- make .lazy() remove the MayAliasBit only, and mark it as deprecated
- add a NoAlias pseudo expression, and MatrixBase::noalias() function
Todo:
- we have to decide whether += and -= assume no aliasing by default ?
- once we agree on the API: update the Sparse module and the unit tests respectively.

22d65d47d0 finally, the good approach was two-sided Jacobi. Indeed, it allows 
to guarantee the precision of the output, which is very valuable.
Here, we guarantee that the diagonal matrix returned by the SVD is
actually diagonal, to machine precision.

Performance isn't bad at all at 50% of the current householder SVD
performance for a 200x200 matrix (no vectorization) and we have
lots of room for improvement.

88147e0a91 big refactoring in Product.h: 
- all specialized products now inherits ProductBase
- the default product evaluated by Assign is still here,
  but it is currently enabled for small fixed sizes only
- => this significantly speed up compilation for large matrices
- I left the OuterProduct specialization empty as an exercise...

3cf5bb31f6 * Bye bye MultiplierBase, extend a bit AnyMatrixBase to allow =, +=, and -= 
* This probably makes ReturnByValue needless
