- Implementation of the simulation of the block decomposed model using sparse matrix using MATLAB code: 
  New option in model : sparse
  Example:
  Model(SPARSE);
  ….
  End;
- Implementation of the simulation of the block decomposed model using sparse matrix for static model. 
- Krylov methods are implemented to solve the linear model J.y=b, with J the Jacobian matrix at each step of  the Newton Method. Two Krylov's solvers are considered : 
   + Generalized Minimum Residual Method (GMRES) 
   + BiConjugate Gradients Stabilized (BICGSTAB)
  To call them the SIMULATE command has to be completed with a new option : METHOD which could have three   different values : 
   + LU : (default value)  Sparse LU resolution
   + GMRES 
   + BICGSTAB
	 	Example:
 			simul(periods=100, method=lu);
                        or        simul(method=Gmres);
- Correction of various bugs in “simulate.dll”.
- Correction of simk.m
- Correction allowing a list of VALUES or PERIODS not necessarily separated by a comma.
