title: How can I save a very large MATLAB sparse matrix to a text file?
body: <p>I have a 30000x14000 sparse matrix in MATLAB (version 7), which I need to use in another program. Calling save won't write this as ASCII (not supported). Calling <code>full()</code> on this monster results in an  <code>Out of Memory</code> error.<br>
  How do I export it?</p>
