title: What does threshold do for a matrix profile?
body: <p><img src="https://i.stack.imgur.com/IlDQb.png" alt="Matrix profiles with both threshold 0.99 and 0" /></p>
  <p>So I've plot these two matrix profiles by using the <code>tsfresh</code> feature extraction libraries and I've verified that these two graphs are identical (through <code>gimp</code>) and now my question is, <code>what does the threshold do, if it's not giving a big impact on the graph</code>? I read that the threshold has to be in between 0 and 1 and these values don't seem to impact this feature.</p>
  <p>Could someone help me understand what the threshold does?</p>
  <p>Thank you!</p>
