title: generate a sequence array in fortran
body: <p>Is there an intrinsic in Fortran that generates an array containing a sequence of numbers from a to b, similar to python's <code>range()</code> </p>
  
  <pre><code>&gt;&gt;&gt; range(1,5)
  [1, 2, 3, 4]
  &gt;&gt;&gt; range(6,10)
  [6, 7, 8, 9]
  </code></pre>
