* * GEMM enhencement: no need to pre-transpose the rhsGravatar Gael Guennebaud2009-07-22
| | | | | | | => 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

* | Add an efficient rank2 update function (like the level2 blas xSYR2 routine).Gravatar Gael Guennebaud2009-07-11
| | | | | | | | Note that it is already used in Tridiagonalization.
| * more sun studio fixesGravatar Gael Guennebaud2009-07-10

| * Set of fixes and workaround to make sun studio more happy.Gravatar Gael Guennebaud2009-07-10
| | | | | | | | Still remains the problem of alignment and vectorization.
* | add a meta unroller for the triangular solver (only for vectors as rhs)Gravatar Gael Guennebaud2009-07-10

* | | commit woking versions of triangular solvers naturallyGravatar Gael Guennebaud2009-07-09
| | | | | | | | | | | | | | | | | | 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...
* | | started to simplify the triangular solversGravatar Gael Guennebaud2009-07-09

* | | ok now all the complex mat-mat and mat-vec products involving conjugate,Gravatar Gael Guennebaud2009-07-08
| | | | | | | | | | | | | | | adjoint, -, and scalar multiple seems to be well handled. It only remains the simpler case: C = alpha*(A*B) ... for the next commit
* | | conjugate expressions are now properly caught by ProductGravatar Gael Guennebaud2009-07-07
| | | | | | | | | | | | | | | => significant speedup in expr. like a.adjoint() * b, for complex scalar type (~ x3)

* | | * change the nesting order of adjoint_return_type toGravatar Gael Guennebaud2009-07-07
| | | | | | | | | | | | | | | | | | 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) * update eigensolver wrt recent changes

| | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* | | * bybye Part, welcome TriangularView and SelfAdjointView.Gravatar Gael Guennebaud2009-07-06
| | | | | | | | | | | | | | | | | | | | | | | | * 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.)
