different eigenvalue error handling for non-numeric input
by Sven Schreiber
Hi,
consider this with gretl 2025a:
<console>
? matrix hello = {1/0} # to get invalid input
? = eigensym(hello)
Not a Number geschah bei Berechnung
? = eigen(hello)
1.#INF
? = svd(hello)
nan
</console>
So we have everything: a hard-stopping error, some IEEE code (?), and a
gretl code. Plus, with a 6x6 matrix input I also saw that eigen() spat
out a "Data error".
I think it would be good if this could be a little harmonized, no?
thanks

new euro area AWM data
by Sven Schreiber
Hi everybody,
with a little delay I've become aware of some work that updates the good
old area-wide model dataset. In gretl we currently ship AWM, AWM17, and
AWM18, and then it wasn't updated anymore at the source. Now there's
˙Ipek and Kısacıko˘glu who offer new data, see
https://mahmuts.bilkent.edu.tr/ and
https://drive.google.com/file/d/1WRyq4iX3KIEFogV_xESpBtdrT7cQLk3c/view?us....
I wonder whether we should ask them if we can convert their Excel file
and ship it with gretl in the future. The "downside" is that they want
to update it regularly, so the question is whether it's too much of a
moving target; plus I just tested the import into gretl, and it works
flawlessy, you only need to tell gretl to use the second (out of three)
sheets in the workfile. So in that sense it could be argued that there
isn't much value added in providing it in gretl format. (Well, from
their dataset you don't get the series descriptions, so that might be
some value added.)

cnameset glitch?
by Sven Schreiber
Hi,
I'm wondering about the following behavior:
<hansl>
matrix mtemp = ones(12) ~ seq(1,12)' # two columns
cnameset(mtemp, "") # works
cnameset(mtemp, " ") # works
cnameset(mtemp, defarray(" "," ")) # works
cnameset(mtemp, defarray("","")) # gives error: Missing string in cnameset
</hansl>
I believe that the 4th/last cnameset line should also apply empty names
to the columns, like the 1st and 2nd lines hopefully do. In contrast and
just for comparison, the 3rd line should apply a single blank character
as the name for each column.
This is with the March 5th snapshot.
thanks

string not marked for translation
by Sven Schreiber
Hi,
I believe that there's a non-translated string for the panel dataset
status line:
in gui/menustate.c line 1076:
s = g_strdup_printf("Panel: units %d:%d, time %s:%s",
u1, u2, st1, st2);
Too late for 2025a I guess, but not a problem, of course.

"--bands" gnuplot option not explicitly listed in ref
by Sven Schreiber
Hi,
the plural "--bands" option for multiple bands in the gnuplot command is
explained in the help text there, but quite hidden. And the option does
not appear in the list of options, only the old singular "--band" does.
So I'd suggest to add that plural option there.
Perhaps it is also time to remove the section "Legacy band syntax" from
the help text? The new stuff was introduced in 2023c.
cheers
