64095b6610 Changed the AnyMatrixBase / ei_special_scalar_op inheritance order as proposed by Gael. 
Added conservativeResizeLike as discussed on the mailing list.

65fe5f76fd rename back MayAliasBit to EvalBeforeAssigningBit 2009-08-16 00:14:05 +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.

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...

7d607048a9 implement a ProductBase class and, as a proof of concept, update TriangularProduct 
and SelfAdjointMatrixProduct to take advantage of it => fewer LOC

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

ec5c608aa3 Set of fixes and workaround to make sun studio more happy. 
Still remains the problem of alignment and vectorization.
 2009-07-10 16:10:03 +02:00

544888e342 add a generic mechanism to copy a special matrix to a dense matrix so that 
we don't need to add other specialization of MatrixBase::operator=, Matrix::=,
and Matrix::Matrix(...)

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.)

03ad303d14 * add resize(int, NoChange) and resize(NoChange, int) 
* add missing assert in resize(int)
* add examples for all resize variants
* expand docs (part of which is from Tim Hutt's e-mail)

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

4f0af00e51 *add missing overloads of setZero, etc... that were mentioned in the tutorial 
--->they go into Matrix as they resize.
*add isConstant() alias to isApproxToConstant()
*extend unit-test
*change an assert into a static assert

e722f55382 fix the Matrix(int,int)/vector 2D ctors issue so that we really 
have a Matrix(Scalar,Scalar) ctor. (useful for std::complex, user
defined types, etc.

1b7b538e05 The ABI break: 
* set AutoAlign=0, DontAlign!=0
* set Dynamic=33331
* add check on fixed sizes
* bump version to 2.0.52

70c0174bf9 * allows fixed size matrix with size==0 (via a specialization of 
MatrixStorage returning a null pointer). For instance this is very
  useful to make Tridiagonalization compile for 1x1 matrices
* fix LLT and eigensolver for 1x1 matrix

6a26506341 add ReturnByValue pseudo expression for in-place evaluation with a 
return-by-value API style (will soon use it for the transform products)

3009d79a1f * allow Matrix to be resized to 0 (solve a lot of troubles with 
some containers)
* new workaround for std::vector which is supposed to work for any
  classes having EIGEN_MAKE_ALIGNED_OPERATOR_NEW as discussed on ML

9bc44094c5 add EIGEN_NO_AUTOMATIC_RESIZING

uninitialized matrices may still be initialized

f6aa60bcf3 centralize those static asserts more upstream, reduces duplication and ensures they can't be bypassed (e.g. 
until now it was possible to bypass the static assert on sizes)

5f43a42ee7 * remove set(), revert to old behavior where = resizes 
* try to be clever in matrix ctors and operator=: be lazy when we can, always allow
  to copy rowvector into columnvector, check the template parameters,
  try to factor the code better
* add missing copy ctor in UnalignedType
* fix bug in the traits of DiagonalProduct
* renaming: EIGEN_TUNE_FOR_CPU_CACHE_SIZE
* update the dox a little
