removing row and column from a List of a List c#
<p>I made a matrix from list of list. How can I remove column 'i' and row 'i'? Is there a method for that? I've tried <code>RemoveAt</code> but that'd remove one item.</p>

<pre><code>List&lt;List&lt;int&gt;&gt; mtx = new List&lt;List&lt;int&gt;&gt;();

  0 1 2 3
  -------
0|0 0 0 0
1|0 0 0 0
2|0 0 0 0
3|0 0 0 0
</code></pre>

<p>For example I would like to delete row i=2</p>
