Re: [Gretl-devel] basic Julia support

In fact, I'm beginning to thing that we ought to provide a Julia package ("GretlLink"?) on pkg.julialang.org for communication with gretl with functions such as the above and more, ideally written by a specialist (Andreas, are you interested?). So in practice, a "using GretlLink" statement would be implicit every time we enter a "foreign" environment, possibly preceded by a 'Pkg.Add("GretlLink")' if necessary.

A couple of Gretl scripts for the same set of tests (parseintperf(),mandelperf(),pisum()) Oleh 21 січня 2016, 09:29:49, від "Riccardo (Jack) Lucchetti" < r.lucchetti(a)univpm.it&gt;: On Wed, 20 Jan 2016, Allin Cottrell wrote: > Perhaps we should offer a prize for the first example of actual time-saving > (and/or improvement in accuracy) in sending a calculation of the sort that > might be required in gretl out to julia for computation.
