0cb4f32e12 implement high level API for SYMM and fix a couple of bugs related to complex 2009-07-22 23:12:22 +02:00
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

d6627d540e * refactoring of the matrix product into multiple small kernels 
* started an efficient selfadjoint matrix * general matrix product
  based on the generic kernels ( => need a very little LOC)

8885d56928 commit woking versions of triangular solvers naturally 
handling conjuagted expression. still have to bench whether it
is faster (runtime and compile time) to directly call the
cache friendly functions, whence all the commented piece of code...

Gael Guennebaud
96e7d9f896 ok now all the complex mat-mat and mat-vec products involving conjugate, 
adjoint, -, and scalar multiple seems to be well handled. It only remains
the simpler case: C = alpha*(A*B) ... for the next commit
 2009-07-08 18:24:37 +02:00

Gael Guennebaud
ea23f36c78 * change the nesting order of adjoint_return_type to 
1 - make it easier to catch conjugate expressions
 2 - make sure there is no unecessary copy (we had NestByValue<Derived> which seems to be very bad)

79877a9917 * take advantage of new possibilies in LLT (mat -= product) 
* fix Block::operator+= product which was not optimized

 2009-07-07 15:32:21 +02:00
Gael Guennebaud
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.)

* rename qr() to householderQr(), for same reason.

6530c8f5b4 A much simplified version of the earlier commit introducing way fewer changes compared to changeset f292d2352e

2b2f0c0220 fix linearRegression, fix doc, add unit test (it was untested since the change 
making fitHyperplane no longer use it)

2829314284 new simplified API to fill sparse matrices (the old functions are 
deprecated). Basically there are now only 2 functions to set a
coefficient:
1) mat.coeffRef(row,col) = value;
2) mat.insert(row,col) = value;
coeffRef has no limitation, insert assumes the coeff has not already
been set, and raises an assert otherwise.
In addition I added a much lower level, but more efficient filling
mechanism for
internal use only.

95bda5e6ab let the user disable alignment altogether by #defining EIGEN_DONT_ALIGN. 
Until now, the user had to edit the source code to do that.
Internally, add EIGEN_ALIGN that takes into account both EIGEN_DONT_ALIGN.and
EIGEN_ARCH_WANTS_ALIGNMENT. From now on, only EIGEN_ALIGN should be used to
test whether we want to align.
