Hi,
my version is 2021b, but the answer in my version is the same as in Artur's version.
The script is the following:

loop while SIMUL <= times
....

    bundle SVMt = ksetup({y, z}, H, F, B, C)
    ...
    #
    mle ll = ERR ? NA : SVMt.llt
    SVMt.obsxmat[1,1] = SVMt.omega
    SVMt.statemat[1,1] = SVMt.beta
    SVMt.statevar[1,2] = SVMt.gamma
    SVMt.statevar[1,3] = exp(SVMt.L2v/2)
    ERR = kfilter(&SVMt)
    params SVMt.omega SVMt.gamma SVMt.beta SVMt.L2v
end mle #--hessian
...
    ksmooth(&SVMt)
...
endloop

If I cancel " ksmooth(&SVMt) " (by #) the script runs well
If I use " ksmooth(&SVMt) ", the script runs well on the first iteration, then the script crashes with the response:

" Argument 1 must point to a state-space bundle

>> ksmooth(&mod) "

That is all!

Best,
Paolo

Hi Jack,

My two pence for the sake of testing.

Your script stops after estimating two models telling:

Argument 1 must point to a state-space bundle

>> ksmooth(&mod)

I'm using gretl 2021d (30/09/21) on macOS Big Sur

Best,

Artur
