Method ao/filtfilt
FILTFILT overrides the filtfilt function for analysis objects.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
DESCRIPTION: FILTFILT overrides the filtfilt function for analysis objects.
Applies the input digital IIR filter to the input analysis object
forwards and backwards. If the input analysis object contains a
time-series (tsdata) then the filter is applied using the normal
recursion algorithm. The output analysis object contains a tsdata
object.
If the input analysis object contains a frequency-series (fsdata)
then the response of the filter is computed and then multiplied
with the input frequency series. The output analysis object
contains a frequency series.
CALL: >> b = filtfilt(a,pl)
INPUTS: pl - a parameter list
a - input analysis object
OUTPUTS:
b - output analysis object containing the filtered data.
PROCINFO: The input filter object with the history values filled in are
always stored with a plist in the 'procinfo' property of the AO.
The key of the plist to get the filter is 'FILTER'.
