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 ;)

cf0f82ecbe sparse module:

Gael Guennebaud
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 !
