Michel Juillard 539bf0ca69 finishing implementation of optional transformation of log and non
integer power arguments   to insure that they are positive
2012-05-26 20:53:48 +02:00
Michel Juillard c6495dfc9d first implementation of transform_logpow. It creates too many auxilary
variables and probably violates Jensen inequality in some cases.

Sébastien Villemot f36f76760a Fix bug where the nth derivative of 0^n evaluated to 0 instead of n!

Michel Juillard ee7078e56c factoring out steady-state computations; steady_state_model now
generates <fname>_steadystate2.m returning parameters as well in case
they have been modified by the user. Added several test cases.

Ferhat Mihoubi 60f7678669 - Substitutes lead for exogenous and endogenous variables in the deterministic case: direct substitution of the variables even in non-linear expressions 2010-09-17 12:17:09 +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
