title: extracting variable from multiple matlab files into one file
body: <p>I have this project task, and I'm having problems solving it.<br>
  I took samples of the words from 1 to 10 spoken by 10 people.
  From each sample I extracted each word e.g, I extracted the word 1 from all samples into different files. I now have 10 files each having the extracted first word. I want to combine these into one single array.</p>
  
  <pre><code>file = wavread( 'G:\Segmented Data\amir.wav');    
  t = linspace(0,8,length(file));    
  t2=linspace(0,.8,8820);    
  section1 = file(1:8820,:);    
  sound(section1, 11025);    
  figure(1),    
  plot(t2,section1);
  </code></pre>
  
  <p>I have 10 files having the above code. I want to extract the variable section from all these into a new file, and store them in an array.</p>
