title: Matlab binary encoding
body: <p>I have a vector containing a series of integers, and what I want to do is take all numbers, convert them into their corresponding binary forms, and concatenate all of the resulting binary values together. Is there any easy way to do this?</p>
  
  <p>e.g. a=[1 2 3 4] --> b=[00000001 00000010 00000011 00000100] --> c=00000001000000100000001100000100</p>
