title: Read from .mat file
body: <p>working with MATLAB, I have a Matrix <code>M</code>, I want to save it in a <code>.mat</code> file then import it and reuse it in my code. I have tried:</p>
  
  <pre><code>save ('file1.mat','M')
  MSaved=load('file1.mat');
  
  Name   | Size    | Bytes | Class  | Attributes
  -------+---------+-------+--------+-----------
  MSaved | 4215x20 | 40744 | double |
  </code></pre>
  
  <p>How can I get access to each cell of the matrix? How to save it again in a matrix?</p>
  
  <p>Need some help, thanks in advance.</p>
