Distanz

pygsp.utils.distanz(x, y=None)

Calculate the distanz between two colon vectors

Parameters:

x : ndarray

First colon vector

y : ndarray

Returns:

d : ndarray

Distance between x and y

Examples

>>> import numpy as np
>>> from pygsp import utils
>>> x = np.random.rand(16)
>>> y = np.random.rand(16)
>>> distanz = utils.distanz(x, y)
