The template parameter of Vector&lt;T&gt; is the element type of the 
vector.  This should an integral, floating point, or complex type.  
These choices of <b>T</b> should work: 
<ul>
<li>bool, char, unsigned char, short int, short unsigned int, int, unsigned int,
long, unsigned long</li>
<li>float, double, long double</li>
<li>complex&lt;float&gt;, complex&lt;double&gt;, and 
complex&lt;long double&gt;</li>
</ul>
Other types
may work provided they have the necessary numeric semantics.
