Re: Help: how to set "nwt" in function filwgts_lancos

Hi Li,

Sure, you can set nwt to 10001, as a larger number of weights will
result in a more accurate filter. But remember, the larger nwt is, the
more points you lose at each end of your timeseries. You will lose 5000
points at each end if you set nwt to 10001...
Good luck,
Adam
