crystal.index
returns an integer sequence of length
n*2^(-j)
.
node.index
returns the integer
(2^j)+b
.
subband.index
returns the sequence integers (2^j):(2^(j+1)-1).
crystal.name.index
returns a matrix of
length(nms)
rows.
If
nms
are 1D crystal names, the matrix has two columns;
If
nms
are 2D crystal names, the matrix has four columns.
qnode.index
returns an integer.
get.parents.quad
returns a matrix with 3 columns and row.names as parent
names of
nms
.
quad.bound
returns a matrix of 4 columns.
wavesubscript.to.index
returns a vector of subscript indices.
crystal.index
is the indeces of the coefficients in the
(j,b)-crystal
,
when sample size is
n
,
defined as `crystal.index(j, b, n) = ((b*n)/2^j + 1):(((b+1)*n)/2^j)'.
node.index
is the index of the
(j,b)-crystal
in a packet table.
subband.index
is the indeces of level
j
crystals in a packet table.
crystal.name.index
computes the indices from crystal names.
qnode.index
computes the quad tree index of 2D crystal
(d, x, y)
,
where
d
is the depth in spliting and
x, y
are coordinates at depth
d
.
get.parents.quad
computes parent crystals of given crystals
nms
.
quad.bound
computes the bounds of 2D crystal
index=(d, x, y)
in an
nr
by
nc
matrix.
wavesubscript.to.index
maps a user subscript to an integer to be used
for subscripting a
crystal.vector
object.
