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

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
