Ferhat Mihoubi 206fff0e71 - 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 1a09426706 - Correction of several bugs with Octave
- Add wrapper needed to compute the steady-state using bytecode and solve_algo = 0, ..., 4
2010-10-22 10:09:07 +02:00
Ferhat Mihoubi 8f36437662 - Extends the algorithms compatible with bytecode to compute the steady-state (ticket #11). The new values for solve_algo are:
* 0: fsolve
   * 1: solve1
   * 2, 4: solve1 + block decomposition
   * 3: csolve
   * 5: LU decomposition with UMFPack (method handling sparse matrix in Matlab)
   * 6: GMRES
   * 7: BiCGStab
   * 8: bytecode own solver (use Gaussian elimination + sparse matrix)

- Bytecode can now evaluate a specific block instead of the overall blocks (new bytecode's option 'Block = block_number')

Ferhat Mihoubi df1b1e4ed0 - In bytecode, the MATLAB function "mexErrMsgTxt" has been replaced by an exception handling see ticket #137 2010-09-24 12:52:58 +02:00

Ferhat Mihoubi c7eff4ba60 - Adding the relaxation method for block and/or bytecode options
- Changing the the stack_solve_algo option :
Previous version             New version
1 : Sparse LU                0 : Sparse LU
2 : GMRES                    1 : Relaxation
3 : BiCGStab                 2 : GMRES
4 : Sparse LU & Optimal Path 3 : BiCGStab
5 : bytecode own solver      4 : Sparse LU & Optimal Path
                             5 : bytecode own solver

Ferhat Mihoubi 77b6096962 - extends the mex_interface: bytecode's debuging purpose
- correction of memory leaks in bytecode
2010-09-17 12:17:14 +02:00
Ferhat Mihoubi 0a3c8a4b0c - compute the jacobian matrix for exogenous, det_exogenous and previous blocks endogenous
- preprocessor provides informations about the dynamic structure of each block
- extends the algorithms available with bytecode: stack_solve_algo = 1, 2, 3 and 4 is compatible the bytecode. Speed and memory requirement are improved with stack_solve_algo = 1 or 4 for large scale models.
- bytecode can be used to evaluate a model

ferhat e1f17fa9e5 - adds a new option in simul command when block and bytecode options are used : minimal_solving_periods. With bytecode option, the linear solver is applied only on the first periods. As soon as the set of operations remains the same from one period to another, they are repeated for the remaining periods. In some cases the linear solver could encounter exact or near singularities. To avoid these effects, this new option allows the user to extend the minimal number of periods where the model has to be solved.
- corrects some mod files.
- In steady command, get check argument from bytecode dll
