Constructor & Destructor Documentation

template<typename T>
Window< T >::Window ( WindowType  type,
int  size 
) [inline]

Construct a windower of the given type and size.

Note that the cosine windows are periodic by design, rather than symmetrical. (A window of size N is equivalent to a symmetrical window of size N+1 with the final element missing.)
