- rename ExprNode::collectVariables in ExprNode::collectDynamicVariables
- new ExprNode::collectVariables: same as above, but without lag information
- remove ExprNode::findUnusedEndogenous: essentially redundant with the above)
- remove ExprNode::collectModelLocalVariables: idem
If the homogeneized equation evaluates to zero, then we skip the
test (otherwise the 2nd derivative of the log is infinite, and the test fails
while it should not necessarily).
Closes#506
Also add a warning in the documentation and in the preprocessor about the usage
of some functions (max, min, abs, sign, comparison operators) in a stochastic
context.
Closes#355
- at the end of the computation, don't display all preprocessor warnings but
only their number
- also display if there has been a MATLAB/Octave warning (counting their
number does not seem feasible). Closes#181
- add new "nowarn" option to disable all warnings. Closes#301
+ the number of static, lag, lead and both variables,
+ the lead_lag_incidence matrix for variables related to previous blocks
+ the index of reordered policy rule
for each block during the preprocessing step
- correct a bug in the comment related to first order derivatives in _dynamic.m file for a block decomposed model without bytcode
- avoid simplification of the Jacobian matrix (setting to zero all elements below the cutoff) for estimated or stochastically simulated models: the cutoff option is set to 0.
- 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

* fixed a bug with EXPECTATION operator: now handle model local variables
* substitute EXPECTATION operator even in deterministic models (for avoiding crashes, even if use of this operator doesn't make sense there)
* forbid the use of EXPECTATION and STEADY_STEATE outside model block
* minor implementation changes in EXPECTATION and STEADY_STATE operators
reference manual:
* documented EXPECTATION and STEADY_STATE operators
* added a note in write_latex_{static,dynamic}_model commands documentation about auxiliary variables and other model transformations
git-svn-id: https://www.dynare.org/svn/dynare/trunk@3145 ac1d8469-bf42-47a9-8791-bf33cf982152
* reworked a little bit the implementation
* documented the command in the reference manual
* added a test

* reference manual: documented the new option, fixed XML conformance of the document

* fixed substitution of endogenous with leads >= 2: take into account exogenous with leads in non-linear terms
* fixed substitution of exogenous with leads: take into account other variables with leads in non-linear terms

* In stochastic mode, now transforms the model by removing leads and lags greater or equal to 2 (creating auxiliary variables and equations in the process)
* Information about these variables is in structure M_.aux_vars
* Automatically add the necessary initialization for auxiliary vars after the initval block or load_params_and_steady_state

- the options "sparse_dll" and "sparse" are no more available. They are replaced by combinations of block (for block decomposition) and bytecode (for model stored in a binary file)
- markowitz is now an option of simul and steady commands

- 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)

* StaticModel: added computation of derivatives for block MFS mode
* DynamicModel: catch error codes of mkdir()
* ModelTree: moved "mode" member variable to DynamicModel

* normalizes the static model
* computes its block decomposition, using topological order
* for each block, computes minimum feedback set of variables
* at this stage, only produces text output (no change in the computation of steady state)

* created a distinct expression tree for the static model (thus giving better sharing of sub-expressions and better computation of temporary terms for the static model)
* for that purpose, created StaticModel and DynamicModel classes (ModelTree still persists, but only contains code shared between StaticModel and DynamicModel)
* removed sparse static file (to be later replaced by new algorithm for steady state computation on large models)
git-svn-id: https://www.dynare.org/svn/dynare/trunk@2592 ac1d8469-bf42-47a9-8791-bf33cf982152

* rewritten from scratch ModFile::evalAllExpressions()
* {load,save}_params_and_steady_state moved to NumericalInitialization.{cc,hh}
* fixed bug related to endval block
