94f6f2a7de Add an axis aligned box in the geometry module.
Some naming questions:
- for "extend" we could also think of: "expand", "union", "add"
- same for "clamp": "crop", "intersect"
- same for "contains": "isInside", "intersect"
=> ah "intersect" is conflicting, so that eliminates this one !

e5b8a59cfa Add smart cast functions and ctor with scalar conversion (explicit)
to all classes of the Geometry module. By smart I mean that if current
type == new type, then it returns a const reference to *this => zero overhead

0c5a09d93f some cleaning and doc in ParametrizedLine and HyperPlane
Just a thought: what about ParamLine instead of the verbose ParametrizedLine ?

8ea8b481de As discussed on ML:
* remove the automatic resizing feature of operator =
 * add function Matrix::set() to be used when the previous
   behavior is wanted
 * the default constructor of dynamic-size matrices now
   creates a "null" matrix (data=0, rows = cols = 0)
   instead of a 1x1 matrix
 * fix UnixX typos ;)

3645d6c138 sparse module: add a RandomSetter based on a user defined map implementation
as described on the wiki (one map per N column)
Here's some bench results for the 4 currently supported map impl:
std::map =>             18.3385 (581 MB)
gnu::hash_map =>        6.52574 (555 MB)
google::dense =>        2.87982 (315 MB)
google::sparse =>       15.7441 (165 MB)
This is the time is second (and memory consumption) to insert/lookup
10 million of coeffs with random coords inside a 10000^2 matrix,
with one map per packet of 64 columns => google::dense really rocks !
Note I use for the key value the index of the column in the packet (between 0 and 63)
times the number of rows and I used the default hash function.... so maybe there is
room for improvement here....

f44316e5f8 UmfPack support: add support for complex<double> 2008-10-20 00:39:11 +00:00
Gael Guennebaud
3a231c2349 sparse module: add support for umfpack, the sparse direct LU
solver from suitesparse (as cholmod). It seems to be even faster
than SuperLU and it was much simpler to interface ! Well,
the factorization is faster, but for the solve part, SuperLU is
quite faster. On the other hand the solve part represents only a
fraction of the whole procedure. Moreover, I bench random matrices
that does not represents real cases, and I'm not sure at all
I use both libraries with their best settings !

ecc6c43dba sparse module: add preliminary support for direct sparse LU solver
using SuperLU. Calling SuperLU was very painful, but it was worth it,
it seems to be damn fast !

e747b338ee Started the third chapter of the tutorial on linear solvers.
It is only a first draft and I think it should be reorganized a bit in 2 parts:
1 - a compact table summarizing the main API and its use
    (this is what would expect an "expert" user)
2 - a discussion about the various algorithm in Eigen to guide the newbies in linear algebra
Currently I mixed the discussion with the API, but it is still better than nothing !

765219aa51 Big API change in Cholesky module:
* rename Cholesky to LLT
 * rename CholeskyWithoutSquareRoot to LDLT
 * rename MatrixBase::cholesky() to llt()
 * rename MatrixBase::choleskyNoSqrt() to ldlt()
 * make {LLT,LDLT}::solve() API consistent with other modules

Note that we are going to keep a source compatibility untill the next beta release.
E.g., the "old" Cholesky* classes, etc are still available for some time.
To be clear, Eigen beta2 should be (hopefully) source compatible with beta1,
and so beta2 will contain all the deprecated API of beta1. Those features marked
as deprecated will be removed in beta3 (or in the final 2.0 if there is no beta 3 !).

Also includes various updated in sparse Cholesky.

useless but at least doesn't hurt)
