title: How to multiply two arrays element-wise
body: <p>I need to multiply an array by another array element-wise, just like the Hadamard product of vectors in math. For example:</p>
  
  <pre><code>A = [1,2,3,4]
  B = [2,3,4,5]
  C = A*B = [2,6,12,20]
  </code></pre>
  
  <p>I can't even figure out the code, I've tried doing so element by element but this seems too messy of a solution for me, any ideas?</p>
