[Gretl-users] Problem With Roots Accessor

Dear Allin, I think there's something "strange" with the special accessor $["roots"]. Please take a look at the following Hansl code: <hansl> # Gretl doesn't save the "r" matrix open data9-7 loop i = 1..2 arima $i 1 2 ; QNC matrix r = $["roots"] # overwrites "r" print r endloop # Gretl saves the "r" matrix open data9-7 arima 1 1 2 ; QNC matrix r = $["roots"] print r arima 2 1 2 ; QNC matrix r = $["roots"] # overwrites "r" print r </hansl> I think this is a little bit weird because I can use the same ideia with another kind of accessor: <hansl> open data9-7 loop i = 1..2 arima $i 1 2 ; QNC matrix c = $coeff print c endloop open data9-7 loop i = 1..2 arima $i 1 2 ; QNC matrix t = $test print t endloop open data9-7 loop i = 1..2 arima $i 1 2 ; QNC matrix p = $pvalue print p endloop </hansl> Thanks in advance, Henrique Andrade* *
