The filtfilt(d, x) version in the documentation does not seem to work

The filtfilt() function seems to demand 3 inputs (b, a, x) but the documentation says it can also accept a filter object instead of the b,a coefficients. Is this an error in the documentation or in the filtfilt() function itself?
Thanks, Dan

It appears that filtfilt does not accept any and all dsp toolbox filter objects. I just happened to choose one that it does not accept. When that happens it reverts to the filtfilt.m file that expects 3 arguments so you get an unhelpful error message complaining about insufficient number of arguments.
So my question has been answered.
