abc8c01080 Renamed PlainMatrixType to PlainObject (Array != Matrix). 
Renamed ReturnByValue::ReturnMatrixType ReturnByValue::ReturnType (again, Array != Matrix).

0ca67afe6a finally here is a simple solution making (a*b).diagonal() even faster than a.lazyProduct(b).diagonal() !! 2010-02-10 14:08:47 +01:00

840977529f * as promised, remove the "optimization" for Product::diagonal() 
* add MatrixBase::lazyProduct

9ce1212d7c For the record, here is a solution for (a*b).diagonal, at the cost of extra copies 
if a and/or b as to be evaluated. So in the next commit I'll remove it. A nice
solution would be to evaluate the lhs/rhs into member of the initial product,
but that would be overkill.

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)

8b016e717f get rid of NestParentByRefBit 2010-02-08 16:51:41 +01:00

871698d3aa Introduced NestParentByRefBit and NestByRefBit - this should fix temporaries related to nested products. 
Fixed a few typos and a few warnings.

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

d40c110053 lot of cleaning: 
- clean the *_PUBLIC_INTERFACE_*
- update Diagonal, ReturnByValue, ForceAlignedAccess, UnaryView, etc. to support array
- many other small stuff

832045d363 Warning 4512 (assignment operators could not be generated) is now simply disabled. 
All unimplemented assignment operators have been removed.

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

3c74d6b7d4 Added private, non-implemented assignment operators to functions that don't need them (fixes VC warning on /W4). 2009-09-27 17:03:02 +02:00

b0aa2520f1 * add real scalar * complex matrix, real matrix * complex scalar, 
and complex scalar * real matrix overloads
* allows the inner and outer product specialisations to mix real and complex

fc9480cbb3 bugfix in compute_matrix_flags, optimization in LU, 
improve doc, and workaround aliasing detection in MatrixBase_eval snippet
(not very nice but I don't know how to do it in a better way)

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.

afbd73b5cd overload operartor* with a ProductBase such that "scalar * (mat * mat)" is optimized 
as one could naturally expect

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
