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.

56d00779db more product refactoring 2009-08-06 12:20:02 +02:00
Gael Guennebaud
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

Gael Guennebaud
e7f8e939e2 * GEMM enhencement: no need to pre-transpose the rhs 
=> faster a * b.transpose() product
  => this also fix a bug in a so far untested situation
* SYMM is now ready for use => still have to write the high level
  stuff to convert natural expressions into a call to SYMM

1578421ed1 fix issue #25 : the problem was that we assumed Dynamic was a multiple of a packet size 
(also disable the test of blueNorm)

587029a612 started an implementation of BandMatrix: at least the read/write access 
to the main/sub/super diagonals seems to work well.

Still remains the problem of alignment and vectorization.

92a35c93b2 * extended the cache friendly products to support C = alpha * A * M and C += alpha * A * B 
* this allows to optimize xpr like C -= lazy_product, still have to catch "scalar_product_of_lazy_product"
* started to support conjugate in cache friendly products (very useful to evaluate A * B.adjoint() without
  evaluating B.adjoint() into a temporary
* compilation fix

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.)

e093b43b2c * rename QR to HouseholderQR because really that impacts the API, not just the impl. 
* rename qr() to householderQr(), for same reason.
* clarify that it's non-pivoting, non-rank-revealing, so remove all the rank API, make solve() be void instead of bool, update the docs/test, etc.
* fix warning in SVD
