f5d2317b12 add a blueNorm() function implementing the Blues's stable norm
algorithm. it is currently provided for experimentation
purpose only.

a2087cd7a3 Add an efficient rank2 update function (like the level2 blas xSYR2 routine).
Note that it is already used in Tridiagonalization.

ec5c608aa3 Set of fixes and workaround to make sun studio more happy.
Still remains the problem of alignment and vectorization.

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

13b2dafb50 conjugate expressions are now properly caught by Product
=> significant speedup in expr. like a.adjoint() * b,
   for complex scalar type (~ x3)

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

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

0c2232e5d9 quick reimplementation of SVD from the numeral recipes book:
this is still not Eigen style code but at least it works for
n>m and it is more accurate than the JAMA based version. (I needed
it now, this is why I did that)

6347b1db5b remove sentence "Eigen itself is part of the KDE project."
it never made very precise sense. but now does it still make any?

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.
