binary.rep(j, d)
binary representation of integer
j
, with
d
digits.
fast.reconstruct.wpt
fast reconstruction functoin. It is a supporting
functoin for
reconstruct.dwt
,
reconstruct.wpt
.
filter.length
provides a fast way to get filter length.
filter.start(f)
index of
f[1]
.
is.odd
returns
TRUE
if
x
is an odd integer, and
FALSE
otherwise.
left.bell.fun
computes the "bell" function for cosine packet analysis.
plot.packet
split.name.2d
splits a 2D name into two 1D names.
