title: How to reshape matlab matrices for this example?
body: <p>I have a 40x16 matrix or 8 5x16 one below the other i.e. aligned vertically. 
  I want to get a 5x128 matrix from that such that I align the 8 5x16 matrices horizontally.
  is there an efficient/quicker (rather than the hardcoded for loops) way to do this?</p>
  
  <p>I want the individual 5x16 matrices intact.</p>
