Package has 1608 files and 132 directories. For example, a common step in seismic horizon interpretation is to apply a filter that reduces the high spatial frequencies in the data, which are mostly attributable to noise, and emphasizes the lower frequencies. Given a linear filter (b, a) and initial conditions on the output `y` and the input `x`, return the initial conditions on the state vector zi which is used by `lfilter` to generate the output given the input.
