Ferhat Mihoubi ce07223628 - The Temporary terms management with bytecode when the model is block decomposed and solve_algo<5 is now compatible with octave 
- Gets rid of warning message during the compilation of bytecode

Ferhat Mihoubi 96b6f1bf05 - Corrects the following problem: 
Octave BiCGStab algorithm involves a 0 division in case of a preconditioner equal to the LU decomposition of the A matrix (in a linear system of the form A.x = b).
- The solution:
Checks if the linear system is solved simply using: x_new = x_old + U \ (L \ x_old)
Ticket #11

Ferhat Mihoubi 129303430e The direction is not computed in same way in the dynamic case and in the static case 2010-12-31 16:20:35 +01:00
Ferhat Mihoubi 9cebf270e5 - correction of informations displayed in Solve_one_boundary 2010-10-27 15:30:00 +02:00
Ferhat Mihoubi 39718c8645 - extends steady algorithms to solve_algo=5, 6, 7 and 8 for a block decomposed model without bytcode 
-  solve_algo is reordered =
   * 0: fsolve
   * 1: solve1
   * 2, 4: solve1 + block decomposition
   * 3: csolve
   * 5: bytecode own solver (use Gaussian elimination + sparse matrix)
   * 6: LU decomposition with UMFPack (method handling sparse matrix in Matlab)
   * 7: GMRES
   * 8: BiCGStab

sebastien 0011678cb5 Changes by Ferhat: 
* fix options stack_solve_algo={2,3,4} (closes #68)
* fix crashes for singular normalizations (closes #44) and implement decreasing cutoff
* fail for stack_solve_algo=2 under Octave (because there is no gmres function in Octave)

sebastien 74232e9ee5 * Added new option stack_solve_algo to simul 
* Added solve_algo=5 for steady
* Remove obsolete method option of simul
* Added various checks to avoid unimplemented combinations of bytecode/block/solve_algo/stack_solve_algo

ferhat d32dd99210 - extension of normalization of equations to nonlinear equations 
- mfs: new option for 'steady' and 'model' commands. Determines the equation belonging to the set of feedback variables.
  mfs = 0 => all variables are considered as feedback variables (default value)
  mfs = 1 => using only naturally normalized equation as potential recursive equations (all variables assigned to unnormalized equations are considered as feedback variable)
  mfs = 2 => adding to the set of potential recursive equation with mfs = 1 the linear equation in endogenous variable normalized (all variables assigned to nonlinear unnormalized equations are considered as feedback variable)
  mfs = 3 => adding to the set of potential recursive equation with mfs = 2 the non linear equation in endogenous variable normalized
- correction of few buggs in simulate.dll
- block_mfs_dll: new option for 'steady' command. Use simulate.dll to solve the steady state model (speedup the computation of the steady-state and the homotopy)
