Dear all,
I have a problem to save a transposed matrix in the GUI. I use Gretl 2016a
under Windows 10.
The problem arise after doing the following steps:
0. Load a Gretl-file into the main window.
1. first choose entry /Hinzufügen/Definiere Matrix... in the main window.
2. Give the Name of a new matrix: for example "NeuMatrix" (with Radiobutton
"Aus Reihen erzeugen")
3. Click ok and transfer for example "const" and two other variables of the
window.
4. click ok
5. Go to "Symbolansicht" choosing /Ansicht/Symbolansicht in the
main-window.
6. You will see the icon called "NeuMatrix". take a double-click on the
icon and see the values of the matrix.
7. In this window chose menue-entry Transformieren/Transponieren and you
see the transposed matrix.
8. Try to save the matrix with "speichern unter" or "speichern" -
Gretl
crashes after a short time
Gretl informs: gretl.exe funktioniert nicht mehr. Das Programm wird
aufgrund eines Problems nicht richtig ausgeführt.
(für den Programmierer der Hinweis: Die Anweisung in 0x00007FFE5D72C6D0
verwies auf Arbeitsspeicher beo 0xFFFFFFFFFFFFFFFF. Der Vorgang read konnte
im Arbeitsspeicher nicht ausgeführt werden)
Meaning: the address of the command is not known.
Greetings

Hello again,
going further another problem arised. I generated the product of X'X
(product of transposed matrix with the original matrix). Then I wanted to
invert it ! (Menü:Transformieren/Invertieren). Gretl crashes again.

I can confirm this on Win 7 with the latest snapshot, although it
doesn't seem to happen every time and/or immediately.

I haven't seen this happening (yet). Gretl inverts the matrix alright
for me. (Which doesn't mean I'm doubting your crash.)
If you need to work around this bug urgently after creating the matrix
X, you can do the stuff you need in script form:
<hansl>
matrix XT = X'
matrix XXI = inv(X'X)
</hansl>
But maybe you just wanted to report the bug...
thanks,

Hello Sven,
thank you for the quick answer. I'm aware of doing it within the script-language (and
there exist an example in Allin's User-handbook).
I'm writing a little textbook concerning Gretl and I want to demonstrate that it's
possible to generate the estimators of a model using only the GUI. Having the matrix
(X'X), inverting it and then multiplying it with the matrices X' and Y(y-values)
gives the estimators. That's very easy in the script and I want to demstrate it, But
it's interesting to demstrate it in the GUI. Therefore I wanted to save the
intermediate data and multiply them in the "Gretl-Konsole".
I produced the shut-downs of Gretl several times. I think it's not a problem for many
users, because one uses the script :-))
Best wishes
Jürgen Malitte

A crash is always bad. I'm pretty sure Allin will find the cause quickly
and fix it.
thanks for the report,

thanks for the report,
Yes, fixing a crash is always a high priority. This should be OK now
in git and snapshots.
I'm afraid that GUI matrix-transformation code had not been reviewed
in a long time, and it had drifted out of sync with the underlying
matrix code. Fortunately the fix was just a one-liner.

Thanks a lot, Mr. Cottrell for the immediately response !! :-)))
