Saving graphs
by Henrique Andrade
Dear Gretl Community,
Is there a way to save graphs (as .png or .pdf) when they are
in the "zoom mode" (right click on the graph -> zoom)?
Thanks in advance,

It's very similar in gretl:
nulldata 200
series e = normal()
series y = 0
y = .8*y(-1) + e
Alternatively, there's the filter() function.

issue
by artur tarassow
Dear gretl community,
I am trying to program some dynamic multipliers on gretl.
Unfortunately, I've got some problems. Consider the following part of
the script:
-----------------------------------
scalar h = 60
scalar k = 1
matrix mtheta = {0.035316 ; -0.021316 ; -0.012700}
mtheta
mpsi = zeros(h,k)
mpsi[1,] = mtheta[1,]
mpsi[1+1,] = vphi[1:1]*mpsi[1:1,] + mtheta[1+1,]
mpsi[2+1,] = vphi[1:2]*mpsi[2:1,] + mtheta[2+1,] #Stops here: "Range
2 to 1 is non-positive!"
mpsi[3+1,] = vphi[1:3]*mpsi[3:1,] + mtheta[3+1,]
--------------------------------------------------------------
Unfortunately, the program stops (where it shoudn't) at the marked
stage due to the reason that the computed number becomes non-positive.
Is there any way to circumvent this behaviour?
Thanks in advance!
