Create the named functional. If an order is specified it is used, otherwise the default functional is created with the specified (or default) parameters. Naming is minimum-match, case insensitive. See the separate combine, compound and compiled descriptions for more information on these special cases.

A created functional (or /em function for short, but be aware of possible Glish terminology clashes) will have a set of basic methods, which are described in the functional tool.
- a:=dfs.functional('poly', 2, [1,2,3]) # create a polynomial
- a.f([0,1,2]) # get some values
[1 6 17]
- a.fdf([0,1,2]) # get values and derivatives
[[1:3,]
1 1 0 0
6 1 1 1
17 1 2 4]
- b:=dfs.functional('combi') # a combine
- b.add(a) # with the polynomial
T
- b.f([0,1,2]) # values are same
[1 6 17]
- b.add(b) # add again
T
- b.f([0,1,2]) # as expected from the combination
