title: MATLAB - Add Value at the first column of a matrix
body: <p>I want to add one value at the beginning of a matrix for  example, my matrix is</p>
  
  <pre><code>0,0,0,0,0,0
  0,1,1,1,0,0
  1,0,0,1,0,0
  1,1,1,0,0,0
  </code></pre>
  
  <p>then I want to add '1' or '0' at the first column therefore it will become like this</p>
  
  <pre><code>1,0,0,0,0,0,0
  1,0,1,1,1,0,0
  1,1,0,0,1,0,0
  1,1,1,1,0,0,0
  
  0,0,0,0,0,0,0
  0,0,1,1,1,0,0
  0,1,0,0,1,0,0
  0,1,1,1,0,0,0
  </code></pre>
  
  <p>how can I do that in MATLAB? </p>
