title: Sum of elements in System.Numerics.Vector<T> in .NET 4.6
body: <p>I cannot figure out a way how to get a sum of elements in a vector of  System.Numerics.Vector type.</p>
  
  <pre><code>double sum(System.Numerics.Vector&lt;double&gt; vect)
  {
       // Something like 
       // double sum = 0;
       // foreach e in vect { sum += e; } 
       // return sum;
  
       // Vector.method???
       // For loop ???
  }
  </code></pre>
  
  <p>If it's actually possible? How can I do this?</p>
