Point-in-rectangle testing
<p>I have this matrix </p>

<pre><code>/// as if the create a rectangle
int [][] loc = {
  {5, 15},//(x1, y1)
  {5, 30}, // (x1, y2)
  {20, 15},// (x2, y1)
  {20, 30}, // (x2, y2)
}

// this are the point that i want to check if they are in the rectangular range or not
int [] [] point = {
  {6, 16}, //(x, y)
  {3, 17}, //(x, y)
}
</code></pre>

<p>I want i method that can take the point and search if it in the loc range or not by using 
<code>x1&lt;x&lt;x2</code> and <code>y1&lt;y&lt;y2</code></p>
