<pre class="literalblock">
Compute the distance matrix.

Computes the matrix of all pairwise distances.

Parameters
==========

x : array-like, m by k
y : array-like, n by k
p : float 1&lt;=p&lt;=infinity
Which Minkowski p-norm to use.
threshold : positive integer
If m*n*k&gt;threshold use a python loop instead of creating
a very large temporary.

Returns
=======

result : array-like, m by n
