title: generating matrices with random entries in [0,1) in python
body: <p>I'm working in python and using numpy. I'm using the command:</p>
  <pre><code>numpy.random.random_sample((n,n))
  </code></pre>
  <p>to generate matrices with random values between (0,1). My understanding is that this function should select x $\in$ (0,1) with uniform probability distribution as opposed to say, normal distribution. Can anyone confirm if this I am using it correctly?</p>
