mvpa2.clfs.distance.squared_euclidean_distance(data1, data2=None, weight=None)

Compute weighted euclidean distance matrix between two datasets.


data1 : np.ndarray

first dataset

data2 : np.ndarray

second dataset. If None, compute the euclidean distance between the first dataset versus itself. (Defaults to None)

weight : np.ndarray

vector of weights, each one associated to each dimension of the dataset (Defaults to None)
