i=1;
Un=3;
sd=1.41;
w=exp(-[[i-Un]^2]/2[sd]^2)

You need to use the * operator to multiply in the denominator. E.g.,
w=exp(-(i-Un)^2/(2*sd^2))
If i is not a variable defined by you, it will be interpreted as the imaginary number sqrt(-1).

I would recommend
w = exp(-(i-Un).^2./(2*sd.^2));
as that would be able to work on non-scalars as well.
