d72d538747 merge my Dynamic -> -1 change 2010-06-11 08:04:06 -04:00
Benoit Jacob
bdd7c6c88a change the value of Dynamic to -1, since the index type is now configurable. 
remove EIGEN_ENUM_MIN/MAX, implement new macros instead

aaaade4b3d the Index types change. 
As discussed on the list (too long to explain here).

4ba032c9ab fix grave bug introduced by me: the low-level matrix-vector product functions can't be fed strided vectors, only strided matrices. 2010-04-20 15:59:17 -04:00
Benoit Jacob
92da574ec2 * allow matrix dimensions to be 0 (also at compile time) and provide a specialization 
of ei_matrix_array for size 0
* adapt many xprs to have the right storage order, now that it matters
* add static assert on expressions to check that vector xprs
  have the righ storage order
* adapt ei_plain_matrix_type_(column|row)_major
* implement assignment of selfadjointview to matrix
  (was before failing to compile) and add nestedExpression() methods
* expand product_symm test
* in ei_gemv_selector, use the PlainObject type instead of a custom Matrix<...> type
* fix VectorBlock and Block mistakes

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

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!

e48c3faf25 Fixed the ProductReturnType (at least for UnrolledProducts). 
Fixed operator= (MSVC specific) in Array.

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

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

9a3cae4655 better fix for (v * v') * v, we still have to find a way to reorder it 2009-10-01 13:27:03 +02:00
Benoit Jacob
fa65b09661 add outerproduct coeff(int,int) method. 
This is needed to make this expression work:
(vec1*vec2.transpose())*vec3
Gael, no objection? Seems to make sense as that's fast.

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

49dd5d7847 * add a HouseholderSequence class (not good enough yet for Triadiagonalization and HessenbergDecomposition) 
* rework a bit AnyMatrixBase, and mobe it to a separate file
 2009-09-16 14:35:42 +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
 2009-09-04 11:22:32 +02:00
Gael Guennebaud
3eb37fe1fb update mixingtype unit test to reflect current status, but it is still clear 
we should allow matrix products between complex and real ?
