Parameters
|
|
L
|
-
|
differential operator
|
domain

Description
|
|
•
|
The input is a differential operator L with rational function coefficients.
|
•
|
The output is a list of irreducible factors such that .
|
•
|
If the argument domain is omitted then the differential specified by the environment variable _Envdiffopdomain will be used. If this environment variable is not set then the argument domain may not be omitted.
|
•
|
This function is part of the DEtools package, and so it can be used in the form DFactor(..) only after executing the command with(DEtools). However, it can always be accessed through the long form of the command by using DEtools[DFactor](..).
