Add a functional to a combi or compound functional

Synopsis
add(x)

Arguments

x	in	functional to be added
		Allowed:	functional

Returns
bool

Description

Add another functional to a combi or compound functional.

Example

- a:=dfs.poly(2,[1,2,3])        # a polynomial
- a.f(1)                        # its value at x=1
6 
- b:=dfs.gaussian1d(10, 0.5, 1) # a Gaussian with height, center, width
- b.f(1)
5 
- c:=dfs.combi(); c.add(a); c.add(b)  # combine them
T 
T 
- c.f(1)                        # value is the sum (default
parameters are 1)
11 
- c.setpar(1, 2.5)              # set the first parameter of combi
to 2.5
[2.5 1]  
- c.f(1)                        # now value is 2.5*poly + 1*gauss
