Method Details

### discrete (self, points, fraction=None) |
Compute the `forward, discrete Fréchet` distance. Arguments: `points` - Second set of points (`LatLon`[], Numpy2LatLon[], Tuple2LatLon[] or `other`[]). `fraction` - Index fraction (`float` in EPS..EPS1) to interpolate intermediate `points` or use `None`, `0` or `1` for no intermediate `points` and no fractional indices. Returns: A Frechet6Tuple`(fd, fi1, fi2, r, n, units)`. Raises: `FrechetError` - Insufficient number of `points` or invalid `fraction`. `RecursionError` - Recursion depth exceeded, see sys.getrecursionlimit(). Overrides: Frechet.discrete
