title: How do you tile a tensor with a decreasing amount of elements/values?
body: <p>For eg, if I had a tensor x as:</p>
  
  <pre><code>[[1.0, 2.0, 3.0]]
  </code></pre>
  
  <p>I would like to get a tensor y as:</p>
  
  <pre><code>[[1.0, 2.0, 3.0], [1.0, 2.0, 0.0], [1.0, 0.0, 0.0]]
  </code></pre>
  
  <p>I've tried using <strong>tf.tile()</strong> but that just copies a tensor's dimension exactly as it is. I was wondering if there is a way to do this using just Tensor Transformations without any looping structures...</p>
