The algorithms for the taper functions are given in the
S+WAVELETS User's Manual,
in the section "Cosine Packet Algorithms". They are discussed in
greater depth in Wickerhauser (1994).
Generic functions such as
print, plot, summary, support
have methods to show the
properties of the
cosine.packet
object.
