Computes the pairwise distance between input vectors, or between columns of input matrices. Distances are computed using p -norm, with constant eps added to avoid division by zero if p is negative, i.e.: \mathrm {dist}\left (x, y\right) = \left\Vert x-y + \epsilon e \right\Vert_p, dist(x,y)= ∥x−y +ϵe∥p, where e e is the ...
