#35: Putting "shocks" before "endval" leads to wrong results --------------------------+------------------------------------------------- Reporter: sebastien | Owner: Type: bug | Status: new Priority: major | Milestone: 4.1 Component: Core M-files | Version: 4.0.4 Keywords: | --------------------------+------------------------------------------------- In a deterministic setup with both temporary and permanent shocks, the order of the {{{shocks}}} and {{{endval}}} blocks matter. Actually, putting {{{shocks}}} before {{{endval}}} leads to wrong results. {{{shocks}}} uses {{{set_shocks.m}}}, which fills in {{{oo_.exo_simul}}}; the point is that, if {{{endval}}} has not been used, this structure is empty, so {{{set_shocks}}} fills it, at date of shocks, for ''all'' the exogenous, and using the ''initial'' steady state value. When {{{simul}}} is finally called, it completes {{{oo_.exo_simul}}} with the ''final'' exogenous steady state, but only for those periods which have no temporary shocks. So at the dates with temporary shocks, the value of exogenous which are permanently shocked is wrong. A quick fix is to forbid the use of {{{shocks}}} before {{{endval}}}. A cleaner fix is to modify {{{set_shocks.m}}} so that it only sets values for the exogenous which are temporarily shocked, and leaves {{{NaN}}} for other exogenous. It would be {{{simul}}}'s job to fill in the holes. -- Ticket URL: <https://www.dynare.org/trac/ticket/35> Dynare <http://www.dynare.org> The Dynare project

#59: add errors to print_info.m --------------------------+------------------------------------------------- Reporter: michel | Owner: Type: bug | Status: new Priority: critical | Milestone: Component: Core M-files | Version: Keywords: | --------------------------+------------------------------------------------- info(1) == 43 (covariance matrix of shocks is not positive definite) should be added to print_info.m We need to check that all error numbers that can be present in info(1) are taken care of. We need to check with grep info *.m -- Ticket URL: <https://www.dynare.org/trac/ticket/59> Dynare <http://www.dynare.org> The Dynare project

[Trac] #38: Create an entry point in bytecode interpreter for use by k-order DLL

#38: Create an entry point in bytecode interpreter for use by k-order DLL --------------------------+------------------------------------------------- Reporter: sebastien | Owner: sebastien Type: feature | Status: new Priority: major | Milestone: Component: Preprocessor | Version: Keywords: | --------------------------+------------------------------------------------- First, support for k-order derivatives computation needs to be added to the preprocessor. Second, a storage mechanism for these needs to be added in the bytecode generation. Third, the bytecode interpreter should provide two C functions: * one for retrieving the number of non-zero elements (NNZE) in the k-order derivative (accross all equations) * one which would pass on the derivatives to the caller. Its arguments would be: * the order of derivation (k) * a (double*) vector, allocated by the caller, of length the NNZE * a (int*) matrix, of size NNZE times (k+1): the first column is the equation number, the others are the variables indices (ordered in non- decreasing order: the symmetric elements are not duplicated) -- Ticket URL: <https://www.dynare.org/trac/ticket/38> Dynare <http://www.dynare.org> The Dynare project
