objects. See below for details.
crystal.list
object, each coefficient (interior and boundary) of which
will be the result of applying the
operator to the corresponding coefficients from both of the arguments.
All the attributes of the
crystal.list
objects must match exactly, e.g.
they must have the same sample sizes, same resolution levels, same
boundary rules, same wavelet filters (for wavelet packet analysis) or tapering
functions (for cosine packet analysis).
The operation is applied to the corresponding pairs of crystals.
If the crystal does not inherit from
wp.inf.crystal
,
then the default method is applied to the vector of coefficients.
If the crystal inherits from
wp.inf.crystal
,
then the default method is applied separately to the
interior coefficients, the left boundary
coefficients and the right boundary coefficients.
Arithmetic operations will fail if there are any non-numeric coefficients.
This is a group method for the functions of the
Ops
group,
the basic operators for arithmetic, comparison, and logic.
Unary operators
-
(sign reverse) and ! (exclusion) are not working.
Use
0-e1
for sign reverse, and
1-e1
for logical exclusion.
