f3fde74695 finalize trsm: works in all situations, and it is now used by solve() and solveInPlace() 2009-07-26 13:01:37 +02:00

282e18da49 ok, now trsm works very well for upper triangular matrices 
TODO: link it with the meta triangular_solve_selector and handle
the case where the rhs is row major by copying it to a col-major
temporary + handle right solving: X = B * M^-1

f4112dcff3 The new trsm is working very very well (read very fast) for 
lower triangular matrix and row or col major lhs.
TODO: handle upper triangular and row major rhs cases

a81388fae9 Implement efficient sefladjoint product (aka SYRK) : C += alpha * U U^T 
It is currently available via SelfAdjointView::rankKupdate.
TODO: allows to write SelfAdjointView += u * u.adjoint()

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
