Random sampling
===============

This class creates random samples from a uniform distribution over the design space.

Usage
-----

.. code-block:: python

  import numpy as np
  import matplotlib.pyplot as plt
  
  from smt.sampling_methods import Random
  
  xlimits = np.array([[0.0, 4.0], [0.0, 3.0]])
  sampling = Random(xlimits=xlimits)
  
  num = 50
  x = sampling(num)
  
  print(x.shape)
  
  plt.plot(x[:, 0], x[:, 1], "o")
  plt.xlabel("x")
  plt.ylabel("y")
  plt.show()
