pwtools.rbf.core.Rbf.get_distsq

Rbf.get_distsq(points=None)[source]

Matrix of distance values \(R_{ij} = |\mathbf x_i - \mathbf c_j|\).

\(\mathbf x_i\) : points[i,:] (points)
\(\mathbf c_j\) : self.points[j,:] (centers)
Parameters:

points (array (K,N) with N-dim points, optional) – If None then self.points is used (training points).

Returns:

distsq

Return type:

(M,K), where K = M for training
