Treatment of symmetric elements in parameters derivatives
by Sébastien Villemot 22 Nov '18

22 Nov '18

Hi, I just made a change in the way the preprocessor treats symmetric elements in parameters derivatives. For consistency with other outputs, the "hp" matrix (derivatives of hessian w.r.t. parameters) now contains the two symmetric elements (when the two endogenous indices are different). Previously it was only containing one half of the elements. The other matrices ("rpp" and "gpp") are unchanged: they were already containing the two symmetric elements (when the two parameters indices are different). I pushed a commit (efec6646) that implements the change in getH.m. Please double check that I did not break anything.

Minimal required MATLAB version is now 7.9 (R2009b)
by Sébastien Villemot 13 Nov '18

13 Nov '18

Hi, We have decided to raise the minimal required MATLAB version to 7.9 (R2009b). This applies to the master branch and to the upcoming 4.6 release (but not on the stable/4.5 branch). In particular, this means that it is now possible to use the tilde (~) syntax for ignored output and input arguments. I have modernized the code using this syntax where I could easily identify that it was possible (i.e. where “junk” was used as the name of the ignored argument).

Building Dynare under Windows
by Sébastien Villemot 12 Nov '18

12 Nov '18

Hi all, I have added in the README.md file a section explaining how to build Dynare from Windows, using the excellent MSYS2 environment. This tool provides a convenient environment for building native Windows binaries, using a setup very close to the one we use for cross-building the official Dynare package. The only drawback is that it cannot compile all the docs (MSYS2 does not include Texlive), and so far I haven't succeded in building the MEX for Octave (it may be feasible, but clearly more work and tweaks are needed). If you are working under Windows, I therefore encourage you to test and possibly use MSYS2. Johannes: some time ago you contributed instructions for building Dynare in the Windows Subsystem for Linux. These instructions are probably outdated, because the version of Ubuntu mentioned there has no C++14 support. And I am quite surprised that you are able to compile MEX files for MATLAB in this environment, unless you are maybe using a cross-compiler? (in which case it should be documented) So these instructions should probably be updated or, if they're no longer relevant, removed.

Many thanks Michel. This must be declared as an external funcion in dynare? Best Marco Sent from Nine Work<http://www.9folders.com/> ________________________________ Da: Michel Juillard <michel.juillard(a)mjui.fr> Inviato: venerdì 9 novembre 2018 13:32 A: List for Dynare developers Oggetto: Re: [DynareDev] fzero in steady state file Hi Marco, no I don't confirm. The alternative is to put the code around the call to fzero in a separate Matlab function and call this function from the steday_state_model block. We can talk about it next week Best Michel Marco.RATTO(a)ec.europa.eu writes: > Dear All, > do you confirm that the only way to use solvers like fzero in st state computation is to write the external matlab steady state file, skipping the steady_state_model block? > many thanks for your advice > best > Marco > --- > Marco Ratto, > Finance and Economy > Joint Research Centre > European Commission, > TP 361, 21027 ISPRA(VA), ITALY > Tel: +39 0332 78 3794 Fax: +39 0332 78 5752, > marco.ratto(a)ec.europa.eu > _______________________________________________ > Dev mailing list > Dev(a)dynare.org > https://eris.dynare.org/cgi-bin/mailman/listinfo/dev -- Michel Juillard _______________________________________________ Dev mailing list Dev(a)dynare.org https://eris.dynare.org/cgi-bin/mailman/listinfo/dev

fzero in steady state file
by Marco.RATTO＠ec.europa.eu 09 Nov '18

Dear All, do you confirm that the only way to use solvers like fzero in st state computation is to write the external matlab steady state file, skipping the steady_state_model block? many thanks for your advice best Marco --- Marco Ratto, Finance and Economy Joint Research Centre European Commission, TP 361, 21027 ISPRA(VA), ITALY Tel: +39 0332 78 3794 Fax: +39 0332 78 5752, marco.ratto(a)ec.europa.eu

fzero in steady state computation
by Marco.RATTO＠ec.europa.eu 09 Nov '18

09 Nov '18

Dear All, do you confirm that the only way to use solvers like fzero in steady state computations is to use the external matlab steady state file, without using the steady_state_model block? i.e. in steady_state_model we cannot use fzero? many thanks for your advice best Marco --- Marco Ratto, Finance and Economy Joint Research Centre European Commission, TP 361, 21027 ISPRA(VA), ITALY Tel: +39 0332 78 3794 Fax: +39 0332 78 5752, marco.ratto(a)ec.europa.eu
