I want to implement a function like this:
myFunction[f_,x_,n_Integer]:=
Module[Join[Array[a,n+1,0],{z,expr}],
<<<< some code to construct a polynomial in x of degree n with
coefficients a[0]...a[n] >>>>>
]
Now Mathematica complains Join[...] is not a list.
But if I type
In= Join[Array[a,2,0],{z,expr}]//FullForm
Out=List[a[0],a[1],z,expr]
It _is_ a List.
Changing n+1 to a number e.g 20 doesn't change Mathematicas behavior.
All what helped, was
Module{u=Array[a,n+1,0],z,expr}, .....
but now the a[i] are global.
Is there a way to get what I want?
