c4c70669d1 Big rewrite in the Sparse module: SparseMatrixBase no longer inherits MatrixBase. 
That means a lot of features which were available for sparse matrices
via the dense (and super slow) implemention are no longer available.
All features which make sense for sparse matrices (aka can be implemented efficiently) will be
implemented soon, but don't expect to see an API as rich as for the dense path.
Other changes:
* no block(), row(), col() anymore.
* instead use .innerVector() to get a col or row vector of a matrix.
* .segment(), start(), end() will be back soon, not sure for block()
* faster cwise product

335d3bcf05 Based on code + help from Alex Stapleton: 
*Add Eigen/StdVector header.
Including it #includes<vector> and "Core" and generates a partial
specialization of std::vector<T> for T=Eigen::Matrix<...>
that will work even with vectorizable fixed-size Eigen types
(working around a design issue in the c++ STL)
*Add unit-test

fd831d5a12 * implement handmade aligned malloc, fast but always wastes 16 bytes of memory. 
only used as fallback for now, needs benchmarking.
  also notice that some malloc() impls do waste memory to keep track of alignment
  and other stuff (check msdn's page on malloc).
* expand test_dynalloc to cover low level aligned alloc funcs. Remove the old
  #ifdef EIGEN_VECTORIZE...
* rewrite the logic choosing an aligned alloc, some new stuff:
  * malloc() already aligned on freebsd and windows x64 (plus apple already)
  * _mm_malloc() used only if EIGEN_VECTORIZE
  * posix_memalign: correct detection according to man page (not necessarily
    linux specific), don't attempt to declare it if the platform didn't declare it
    (there had to be a reason why it didn't declare it, right?)

f52a9e5315 * Added aligned_allocator for using 16-byte aligned types with STL containers. There is still a compile-time problem with STL containers that have a standard-conformant resize() method, but this should resolve the original user issue which was storing aligned objects in a std::map. 2009-01-09 00:55:53 +00:00
