6530c8f5b4 A much simplified version of the earlier commit introducing way fewer changes compared to changeset f292d2352e 
.
The reason of the previous commit was incorrect. The smart pointers issues were actually a result of issue 9.
 2009-06-03 22:22:15 +02:00
Hauke Heibel
71e5cbcbc4 Added specializations for DontAlign when using Dynamic matrices. 
This allows users to store Matrices in smart pointers without the
need for a specialized allocator/de-allocator.

7c14e1eac4 add partial-pivoting LU decomposition 
the name 'PartialLU' is not meant to be definitive!
make inverse() and determinant() use it, so it's *almost* considered
well tested.

5b364a68cb oops 2009-05-04 14:53:21 +00:00
Gael Guennebaud
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.
