Calling Functions Vectors Array

Suppose I have the following function:

function c = relation( n )
if n==0
   c = 1;
elseif n==1   
   syms x
   c = [x 0];
else
   syms x
   c = ((2*n-1)*x*[relation(n-1),0] - (n-1)*[0,0,relation(n-2)])/n;
   sum(c)
end

Suppose I choose n = 8, c will output an array but that's not useful to me. I want to plot the polynomial, so I use sum(c) and copy and paste the output and plot it. Is there a way to call 'c' ?

   syms x
   c1 = ((2*n-1)*x*[relation(n-1),0] - (n-1)*[0,0,relation(n-2)])/n;
   c=sum(c1)

I get errors with those commands:

??? Error using ==> mupadmex
Error in MuPAD command: Array sizes must match.

Error in ==> sym.minus at 14
    X = mupadmex('mllib::zip',A.s,B.s,'_subtract');

Error in ==> relation at 9
   c1 = ((2*n-1)*x*[relation(n-1),0] - (n-1)*[0,0,relation(n-2)])/n;
