Description
|
|
•
|
An element L in C(x)[Dx] corresponds to a linear homogeneous differential equation . These two procedures convert between the operator L and the equation . See also the help page diffop on linear differential operators.

•
|
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.

These functions are part of the DEtools package, and so they can be used in the form de2diffop(..) and diffop2de(..) only after executing the command with(DEtools). However, they can always be accessed through the long form of the command by using DEtools[de2diffop](..) or DEtools[diffop2de](..).
