ize Zero Arrays</h3>
<p>If any of an array’s dimensions is size zero, the entire array will be
of size zero. That is, if we declare</p>
<pre class="stan"><code>real a[3, 0];</code></pre>
<p>then the resulting size of <code>a</code> is zero and querying any of its
dimensions at run time will result in the value zero. Declared as
above, <code>a[1]</code> will be a size-zero one-dimensional array. For
comparison, declaring</p>
<pre class="stan"><code>real b[0, 3];</code></pre>
<p>also produces an array with
