NAME

Halfint - half order integeral filter


SYNOPSIS

Halfint conj=0 inv=0 < in.H > out.H


INPUT PARAMETERS

inv - integer
        [0]: half-order integrator .
          1: half-order differentiator .
conj- integer
        [0]: causal .
          1: anticausal .
rho - real
        [1-2/n1]: constant for leaky integration .
n1,n2,n3- integer
        cube dimensions


DESCRIPTION

  half-order integral filter on 1-axis with conjugate and inverse.
  computation in the Fourier domain.


EXAMPLE

                Halfint < in.H conj=0 inv=1 > out.H
                computes the causal half-order derivative of the input data
