scipy.spatial.distance.is_valid_y

scipy.spatial.distance.is_valid_y(y, warning=False, throw=False, name=None)

Returns True if the variable y passed is a valid condensed distance matrix. Condensed distance matrices must be 1-dimensional numpy arrays containing doubles. Their length must be a binomial coefficient {n \choose 2} for some positive integer n.

Parameters :

y : ndarray

The condensed distance matrix.

warning : bool, optional

Invokes a warning if the variable passed is not a valid condensed distance matrix. The warning message explains why the distance matrix is not valid. ‘name’ is used when referencing the offending variable.

throws : throw, optional

Throws an exception if the variable passed is not a valid condensed distance matrix.

name : bool, optional

Used when referencing the offending variable in the warning or exception message.
