filtfilt error solved?

[seektime]

Hi,


I'd like to use the filtfilt function in the signal proc. TB. Unfortunately,
running the example from help section throws the following error:

octave:129> [b, a]=butter(3, 0.1);
octave:130> t = 0:0.01:1.0;
octave:131> x=sin(2*pi*t*2.3)+0.25*randn(size(t));
octave:132> y = filtfilt(b,a,x);
error: filter: first dimension of SI must be of length max (length (a), 
length (b)) - 1
error: called from:
error:
C:\Octave\3.4.3_gcc-4.5.2\Octave3.4.3_gcc4.5.2\share\octave\packages\si
gnal-1.1.1\filtfilt.m at line 85, column 3

I read in a previous post that the problem lies with 'filter.m', but that
seemed to refer to ver. 3.4.2. I'm running Octave 3.4.3 (mingw). Is there's
a quick fix? Any ideas or solutions are highly welcome. 

Thanks,
Michael
