9251cfed9b this had to be done here, not at the end. 2010-02-12 09:03:16 -05:00

37ca4200b2 Piotr's patch was missing many occurences of size_t. So, 
using std::size_t;
This is the only way that we can ensure QCC support in the long term without having to think about it everytime.

5686eca7b1 * fix multiple temporary copies for coeff based products 
* introduce a lazy product version of the coefficient based implementation
  => flagged is not used anymore
  => small outer product are now lazy by default (aliasing is really unlikely for outer products)

73eb0e633c * resurected Flagged from Eigen2Support 
* reimplement .diagonal() for ProductBase to make (A*B).diagonal() more efficient!

ebb2878829 finally add a Array class with storage via the introduction of a DenseStorageBase 
base class shared by both Matrix and Array

4af1753b6f * remove EnforceAlignedAccess option to Block, VectorBlock, Map and MapBase 
because thanks to the previous commit this is not needed anymore
* add a more general ForceAlignedAccess expression which can be used for any expression.
  It is already used by StableNorm.h.

eb8f450071 Hey, finally the copyCoeff stuff is not only used to implement swap anymore :) 
Add an internal pseudo expression allowing to optimize operators like +=, *= using
the copyCoeff stuff.
This allows to easily enforce aligned load for the destination matrix everywhere.

e3d890bc5a Another big refactoring change: 
* add a new Eigen2Support module including Cwise, Flagged, and some other deprecated stuff
* add a few cwiseXxx functions
* adapt a few modules to use cwiseXxx instead of the .cwise() prefix
 2009-11-18 18:15:19 +01:00

1e62e0b0d8 more ET refactoring: 
* extend Cwise for multiple storage base class
* a lot of cleaning in the Sparse module

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

7b0c4102fa * add a Make* expression type builder to allow the 
construction of generic expressions working
  for both dense and sparse matrix. A nicer solution
  would be to use CwiseBinaryOp for any kind of matrix.
  To this end we either need to change the overall design
  so that the base class(es) depends on the kind of matrix,
  or we could add a template parameter to each expression
  type (e.g., int Kind = ei_traits<MatrixType>::Kind)
  allowing to specialize each expression for each kind of matrix.
* Extend AutoDiffScalar to work with sparse vector expression
  for the derivatives.

* rework a bit AnyMatrixBase, and mobe it to a separate file

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.

to the main/sub/super diagonals seems to work well.

1aea45335f * bybye Part, welcome TriangularView and SelfAdjointView. 
* move solveTriangular*() to TriangularView::solve*()
* move .llt() to SelfAdjointView
* add a high level wrapper to the efficient selfadjoint * vector product
* improve LLT so that we can specify which triangular part is meaningless
=> there are still many things to do (doc, cleaning, improve the matrix products, etc.)
