70c0174bf9 * allows fixed size matrix with size==0 (via a specialization of 
MatrixStorage returning a null pointer). For instance this is very
  useful to make Tridiagonalization compile for 1x1 matrices
* fix LLT and eigensolver for 1x1 matrix

fbf415c547 add vectorization of unary operator-() (the AltiVec version is probably 
broken)

vectorized)

c087373968 because of a missing specialization, operator/(scalar) was not vectorized 2009-03-09 23:14:53 +00:00

too high

0be89a4796 big addons: 
* add Homogeneous expression for vector and set of vectors (aka matrix)
  => the next step will be to overload operator*
* add homogeneous normalization (again for vector and set of vectors)
* add a Replicate expression (with uni-directional replication
  facilities)
=> for all of them I'll add examples once we agree on the API
* fix gcc-4.4 warnings
* rename reverse.cpp array_reverse.cpp

6a26506341 add ReturnByValue pseudo expression for in-place evaluation with a

de014efdaf * split CacheFriendlyProduct into multiple smaller files 
* add an efficient selfadjoint * vector implementation (= blas symv)
  perf are inbetween MKL and GOTO
  => the interface is still missing (have to be rethougth)

752d95c20e eventually c++ does not provide any optimized pow(int,int) function, 
so here you go :) (should also fix Timothy's troubles)

3009d79a1f * allow Matrix to be resized to 0 (solve a lot of troubles with 
some containers)
* new workaround for std::vector which is supposed to work for any
  classes having EIGEN_MAKE_ALIGNED_OPERATOR_NEW as discussed on ML

Gael Guennebaud
910b387438 Add sub/super-diagonal expression (read/write) as a trivial extension of 
DiagonalCoeffs. The current API is simply:
  m.diagonal<1>() => 1st super diagonal
  m.diagonal<-2>() => the 2nd sub diagonal
I'll add a code snippet once we agree on this API.
