示例1: conv

{
if( X.size()==0 || Y.size()==0 )
return sequence<R>();
vec<R> vec = conv( X.buffer(), Y.buffer() );

}示例2: decltype
sequence<decltype(T()*S())> element_prod( const sequence<T>& X, const sequence<S>& Y )
{
typedef decltype(T()*S()) R;
// If any vector is empty
if( X.size() == 0 || Y.size() == 0 )
return sequence<R>();
// Overlapping interval
int ta = max(X.t1(),Y.t1());
int tb = min(X.t2(),Y.t2());
// If they do not overlap
if( ta > tb )
return sequence<R>();
// They do overlap
vec<R> v = element_prod(
X.buffer()( range( ta-X.t1(), tb-X.t1()+1 ) ),
Y.buffer()( range( ta-Y.t1(), tb-Y.t1()+1 ) ) );

sequence<R> operator+( sequence<T1> X, sequence<T2> Y )
{
if( X.size() == 0 )
return Y;
if( Y.size() == 0 )
return X;
// Intervals

// Second interval

}
// Third interval
