Create lag operator polynomial (LagOp) object
Create a lag operator polynomial A(L), by specifying the coefficients and, optionally, the corresponding lags.
A
=
LagOp(coefficients
)
creates
a lag operator polynomial with additional options specified by one
or more A

,Name,Value
)Name,Value
pair arguments. Name
can
also be a property name and Value
is the corresponding
value. Name
must appear inside single quotes (''
).
You can specify several namevalue pair arguments in any order as Name1,Value1,...,NameN,ValueN
.

The coefficients of the lag operator polynomial. Generally,

Specify optional commaseparated pairs of Name,Value
arguments.
Name
is the argument
name and Value
is the corresponding
value. Name
must appear
inside single quotes (' '
).
You can specify several name and value pair
arguments in any order as Name1,Value1,...,NameN,ValueN
.

Vector of integer lags associated with the polynomial coefficients. If specified, the number of lags must be the same as the number of coefficients. Default: Coefficients are associated with lags 0, 1,..., 

Nonnegative scalar tolerance used to determine which lags are
included in the object. Specifying a tolerance greater than the default
