Question: How do I get the name of the function

Hallo,

I would like to parse function name of parameters (type is function) in my procedure.
I expact for the one parameter this fun::Or(name, function(name). This is exactly the same type like the second parameter in procedure rsolve

For example:
The value of the parameter fun is y(n) and I would like to parse function name y and function variable n.

The function variable is easy

> indets(fun, name)[];

n

but how can I get the name of the function???

Please Wait...
