iterable : iterable
Iterable containing objects to compute pairwise distances on.
metric : callable
A function that takes two arguments and returns a float
representing the distance between the two arguments.
key : callable or metadata key, optional
A function that takes one argument and returns a string
representing the id of the element in the distance matrix.
Alternatively, a key to a metadata property if it exists for
each element in the iterable. If None, then default ids will be
used.
keys : iterable, optional
An iterable of the same length as iterable. Each element will be
used as the respective key.
validate : boolean, optional
If True, all pairwise distances are computed, including upper
and lower triangles and the diagonal, and the resulting matrix is
validated for symmetry and hollowness. If False, metric is
assumed to be hollow and symmetric and only the lower triangle
(excluding the diagonal) is computed. Pass validate=False if
you are sure metric is hollow and symmetric for improved
performance.
