How to read matrix from file in octave?
<p>I am trying to read a matrix from file in Octave but I just can't find a solution.
The input file is:</p>

<pre><code>4
1 4 2 3
1 4 2 1
4 2 1 4
1 2 1 3
</code></pre>

<p>where 4 is the number of rows and columns. I want to be able to store that information in a matrix and to be able to use it's elements by calling them like <code>a(2,3)</code>.</p>
