dyadup
Dyadic upsampling
Description
,
where Y
= dyadup(X
,EVENODD
)X
upsamples even- or odd-indexed elements of
X
. Y
can contain even- or odd-indexed
samples of X
depends on the value of
EVENODD
. Specify X
as a vector. When you
specify X
as a vector, the function returns an extended copy of
vector X
obtained by inserting zeros.
dyadup
implements a simple zero-padding scheme very useful in
the wavelet reconstruction algorithm.
