Plotting Errors

[Ryan Edwards-Crewe]

Hi,

I'm trying to plot the results of this transfer function, but when I do 
I get many errors.

octave:6> gos=tf(1000, [1 2 100], 2);
octave:7> plot(gos)
error: mapper: wrong type argument `struct'
error: evaluating assignment expression near line 47, column 8
error: called from `__plt1__' in file 
`/usr/share/octave/2.9.9/m/plot/__plt1__.m'
error: evaluating if command near line 58, column 4
error: evaluating if command near line 56, column 2
error: evaluating if command near line 55, column 7
error: evaluating while command near line 44, column 5
error: evaluating if command near line 34, column 3
error: called from `__plt__' in file 
`/usr/share/octave/2.9.9/m/plot/__plt__.m'
error: called from `plot' in file `/usr/share/octave/2.9.9/m/plot/plot.m'
octave:7>

don't know what any of this means, any help would be appreciated.
