[julia-users] return in function

[digxx]

So I want to do the following function but it doesnt work.
The problem probably is that I need something like a "return" at the and 
which I incorporated symbolically. Atm the output is empty.

function vk(k,x)

res=zeros(length(x))

if k>=2 && k<=(N-1)

for i=1:length(x)
if x[i]<=X[k] && x[i]>=X[k-1]
res[i]=(x[i]-X[k-1])/(X[k]-X[k-1])
elseif x[i]<=X[k+1] && x[i]>=X[k]
res[i]=(X[k+1]-x[i])/(X[k+1]-X[k])
else
res[i]=0
end
end

else
res[:]=0
end

return, res
end
