* Removed simult_ and added local_state_space_iteration_2 (a specialized version of simult_).
* Renamed gaussian_particle_filter.m. Changed the names of the variables in this file. The gaussian nodes are not stored anymore in a big matrix. * Added a function to compute the cholesky decomposition of a symetric semidefinite positive matrix. git-svn-id: https://www.dynare.org/svn/dynare/trunk@3138 ac1d8469-bf42-47a9-8791-bf33cf982152
