NAME

Filter - filter a dataset


SYNOPSIS

Filter filter=filter.H pad=zero < in.H > out.H


INPUT PARAMETERS

n1,n2,n3 - integer

       cube dimensions (n1<4096)
n1 - integer

       length of the filter(from auxilary file)
pad - string

       zero: pad data with zeros duplicate: pad with samples at ends of data


DESCRIPTION

  Filtering over 1 dimension performed in the frequency domain


COMMENTS

        The length of the data when performing the filtering is zero padded 
        to be the next power of 2 greater than or equal to 
        max(5/4*n1,n1wavelet).  This avoids wraparound artifacts.
