title: Getting a double[] row array of a double[,] rectangular array
body: <p>Suppose you have an array like:</p>
  
  <pre><code>double[,] rectArray = new double[10,3];
  </code></pre>
  
  <p>Now you want the fouth row as a double[] array of 3 elements without doing:</p>
  
  <pre><code>double[] fourthRow = new double[]{rectArray[3,0],
                                    rectArray[3,1], 
                                    rectArray[3,2]};
  </code></pre>
  
  <p>Is it possible someway? Even using a Marshal.Something approach?</p>
  
  <p>Thanks!</p>
