scipy.spatial.distance.is_valid_y(y, warning=False, throw=False, name=None)[source]¶ Return True if the input array is a valid condensed distance matrix.
Condensed distance matrices must be 1-dimensional numpy arrays. Their length must be a binomial coefficient \({n \choose 2}\) for some positive integer n.
- Parameters
- yndarray
The condensed distance matrix.
- warningbool, 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.
- throwbool, optional
Throws an exception if the variable passed is not a valid condensed distance matrix.
- namebool, optional
Used when referencing the offending variable in the warning or exception message.
