Select Atoms from Basis
DESCRIPTION:
Select the atoms which are associated with the biggest coefficients from an orthogonal basis (a
cpt
or
wpt
object).
USAGE
:
top.atoms(basis, n.atom=50)
REQUIRED ARGUMENTS
:
basis
:
an object which inherits from
cpt
or
wpt
.
OPTIONAL ARGUMENTS
:
n.atom
:
number of top atoms to be selected, the default is
n.atom=50
.
VALUE
:
an object of class
cp.molecule
or
wp.molecule
inheriting from the class
molecule
. See
molecule.object
for details.
DETAILS:
The top atoms are selected based on energy.
BUGS:
This function does not work for non-decimated wavelet transforms.
