[Gretl-devel] disappearing matrices
This is going back a few days:
Sven (Wed, 10 Jan 2007)
I run the following command:
matrix weakexo = p4g_vecm_weakexo(endo, 2, 1, 3, 0, 0, \
rexo, 0, uexo)
...and yes, it's there:
? weakexo
weakexo
3.1524 1.0000 0.075816
6.2215 1.0000 0.012621
BUT when I run the script with the function definition
p4g_vecm_weakexo again (and nothing else!), the previous
output disappears:
? weakexo
command 'weakexo' not recognized
Me (also 10 Jan):
The action of running a script clears out gretl's workspace. I
suspect it might be non-trivial to change that behaviour, though
this is something to think about.
I don't know what I was smoking when I wrote that, but the first
statement is rubbish. Simply running a script does _not_ clean
out gretl's workspace, as is easily confirmed by example.
allin@myrtle:~/src/build/cli$ cat testrun.inp
open data4-1
matrix M = I(3)
run r1.inp
print M
allin@myrtle:~/src/build/cli$ cat r1.inp
ols 1 0 2 3 4
run r2.inp
allin@myrtle:~/src/build/cli$ cat r2.inp
omit 3 4
allin@myrtle:~/src/build/cli$ ./gretlcli -b testrun.inp
[ output as expected, culminating in printing of matrix M
after running the scripts r1.inp and r2.inp. ]
The same thing works in the gui program.
On the other hand, opening a new data file _does_ clear out
gretl's workspace. So: Sven, if this is still of interest, could
you put your question again, with a little more detail?
Allin.
