[Gretl-devel] old and new ideas for the next 'extra' addon version

Hi, here are some thoughts about a next round of updating 'extra'. Reminder: "The extra package (a collection of various convenience functions for hansl programming)". It comes as an add-on which means it is automatically shipped with each gretl installation. All items including their names and so on are open for discussion. 1) drawnormwis(): This function does a random draw from Normal-inverse-Wishart distributions for Bayesian stuff and currently exists hidden in the SVAR addon (see https://sourceforge.net/p/gretl/git/ci/master/tree/addons/SVAR/SVAR_compa...) It could go in "as is", unless somebody has suggestions or ideas. 2) multiplot(): I'm attaching an unfinished but working prototype. Many many things could be added here, this is a bit like Pandora's box (or the work of Sisyphus?). But maybe having _something_ is better than nothing? Feedback please! 3) fill() or fill3D() or whatever: Would be the inverse of drill(), i.e. “shoves” a 1-dim vector with N elements into an N-element matrices array (in each i,j position), so in the hole left by drill(), so to speak. Would be easy to arrange, but is there really a need? thanks sven
