This fixes the following bugs:
- 1st and 2nd ext fcn deriv nodes were incorrectly added to
DataTree::external_function_node_map, because of the chaining of
constructors.
- the following methods of FirstDerivExternalFunctionNode were not overloaded:
toStatic(), buildSimilarExternalFunctionNode()
- the following methods of SecondDerivExternalFunctionNode were not overloaded:
toStatic(), buildSimilarExternalFunctionNode(), compile(),
compileExternalFunctionOutput()
Since the method was not implement, the method of the parent class was used.
This was leading to wrong results in the context of Ramsey Policy (basically
derivative operators on external functions were dropped from FOCs).
- 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
- 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
- remove useless output type oMatlabDynamicModelSparseLocalTemporaryTerms
(indistinguishable from oMatlabDynamicModelSparseLocal)
- fix bug in output type of sparse static 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

* reworked a little bit the implementation
* documented the command in the reference manual
* added a test

* 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

- 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)

* new ExprNode method for computing set of ModelLocalVariables of an expression

* sort recursive variables in topological order in the _static.m file
* collectEndogenous() returs type specific IDs, not symb_id!

* StaticModel: dropped creation of C file in USE_DLL mode
* StaticModel: added computation of derivatives for block MFS mode
* DynamicModel: catch error codes of mkdir()
* ModelTree: moved "mode" member variable to DynamicModel
* ModFile::writeOutput(): moved manipulations relative to dynamic model file to DynamicModel
git-svn-id: https://www.dynare.org/svn/dynare/trunk@2818 ac1d8469-bf42-47a9-8791-bf33cf982152
* moved some declarations from ExprNode.hh to BlockTriangular.hh to which they conceptually belong
* replaced non standard boolean operators (and, or, not) by standard ones (&&, ||, !)
git-svn-id: https://www.dynare.org/svn/dynare/trunk@2812 ac1d8469-bf42-47a9-8791-bf33cf982152
* fixed a bug in the handling of VariableNode: we now make a copy of the recursive_variables map, instead of modifying that of the caller
* factorized code shared with standard derivation
* various minor cleanups

- normalize an equation linear in its endogenous variable
- Chained rule derivatives (necessary to reduce a block to the feedback equations and variables)

- First draft of DynamicModel.cc files with feedback variables.
TODO :
- reduction of the Jacobian matrix
- symbolic normalization of equations
- application to the binary code evaluation (simulate.dll).

* 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)
