How to plot using symsum

I was wondering how you correctly plot using the function symsum. I was thinking the following but nothing shows up on the graph:

    syms x
    W = symsum(x/2,x,0,2)
    plot(W)

Any suggestions would be most appreciated!

syms x
k = 1:200 ;
W = zeros(size(k)) ;
for i = 1:length(k)
    W(i) = symsum(x/2,x,0,k(i)) ;
end
plot(k,W)
