scipy.spatial.distance.
num_obs_dm#
- scipy.spatial.distance.num_obs_dm(d)[source]#
Return the number of original observations that correspond to a square, redundant distance matrix.
- Parameters:
- darray_like
The target distance matrix.
- Returns:
- num_obs_dmint
The number of observations in the redundant distance matrix.
Examples
Find the number of original observations corresponding to a square redundant distance matrix d.
>>> from scipy.spatial.distance import num_obs_dm >>> d = [[0, 100, 200], [100, 0, 150], [200, 150, 0]] >>> num_obs_dm(d) 3
