ode> denotes a row vector of
three elements with real values 1.0, 10.0, and 100.0.
Applying the transpose operator to a row vector expression produces
a vector expression.
This syntax provides a way declare and define small vectors a single line, as follows.</p>
<pre class="stan"><code>row_vector[2] rv2=  [ 1, 2 ];
vector[3] v3 = [ 3, 4, 5 ]&#39;;</code></pre>
<p>The vector expression values may be compound expressions
or variable names, so it is legal to write
<code>[ 2 * 3, 1 + 4]</code> or <code>[ x, y ]
