title: How do we represent the Python/numpy function "zeros_like" in Julia language
body: <p>I am a bit new to Julia but I have some knowledge in Python. I am now learning Julia and I want to know how to represent the Python function &quot;zeros_like&quot; from Numpy in Julia.
  The python code is below:</p>
  <pre class="lang-py prettyprint-override"><code>import numpy as np
  a = [3] #vector of one number
  b = np.zeros_like(a)
  </code></pre>
