<p><code>T[,,]</code> <strong><code>rep_array</code></strong><code>(T x, int k, int m, int n)</code><br>
Return the k by m by n array with every entry assigned to x.</p>
<p>For example, <code>rep_array(1.0,5)</code> produces a real array (type <code>real[]</code>)
of size 5 with all values set to 1.0. On the other hand,

with all values set to 1. This distinction is important because it is
not possible to assign
