title: Making n matrixes with repeating numbers
body: <p>I am an new to Python (and programing in general) and wonder if someone could help me out with this one?</p>
  
  <p>I want to make n (1*4) matrixes where the first one is:</p>
  
  <pre><code>[1,2,3,4], 
  </code></pre>
  
  <p>and the next ones </p>
  
  <pre><code>[3,4,5,6],  
  
  [5,6,7,8], 
  
  [7,8,9,10]
  </code></pre>
  
  <p>and so on..</p>
  
  <pre><code>n=70 
  </code></pre>
  
  <p>I have tried this so far but i only get the first 1 and 2 right, and then it repeats!</p>
  
  <pre><code>L2G = np.zeros((70,1,4))
  for i in range(70):
      L2G[i,:,:] = [1,2,3,4]
      if L2G[i,0,0] == L2G[i-1,0,0]:
          L2G[i,:,:] += 2
  </code></pre>
