Generalised inner product and methods for class "MixComp"
inner.Rd
Generalised inner product and methods for class MixComp. The methods for MixComp provide for very convenient computing with MixAR models.
Arguments
- x
the first argument.
- y
the second argument.
- star
function to apply to pairs of elements from
x
andy
, default is multiplication, as for the usual inner product.- plus
function to apply to combine the results from the pairs, default is addition, as for the usual inner product.
Details
inner
computes a generalised inner product x . y
, where
multiplication and summation can be replaced by other functions.
The default method of inner
applies star
to the
corresponding pairs of elements and combines them with plus
.
There is no recycling, if x
and y
have different
lengths, an error is raised. The elements of x
and y
are accessed with "[[". plus
should be an n
-ary
operation.
Methods
Methods for inner product between a "MixComp"
object and a
vector are similar to a product between a matrix and a vector but
comply with the conventions of class "MixComp"
. For this reason
they are described in the help page for class
"MixComp"
, along with methods for other functions
and operators applied to "MixComp"
objects.
signature(x = "ANY", y = "ANY", star = "ANY", plus = "ANY")
This is the default method, see section Details.
signature(x = "MixComp", y = "missing", star = "missing", plus = "missing")

.signature(x = "MixComp", y = "numeric", star = "missing", plus = "missing")
