nsion
of the matrix, leaving only a row dimension index, hence the result is
a vector. In this case, <code>b[j] == a[1, 3, 1 + j, 2]</code>.</p>
<p>This last example illustrates an important point: if there is a
lower-bounded index, such as <code>2:3</code>, with lower bound 2, then the
lower bound minus one is added to the index, as seen in the <code>1 + j</code> expression above.</p>
<p>Continuing further, consider continuing with the following.</p>
<pre><code>...
row_vector[3] c[2];
c = a[4:5, 3, 1, 2: ]
