pwtools.rbf.core.Rbf.get_distsq

Rbf.get_distsq(points=None)

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
