When i try to create function error "Unable to perform assignment because the left and right sides have a different number of elements." comes up

I want to create x3=e^(j(1/2)n) for 2<=n<=22

The code i used was:

n=-25:25

x3=zeros(1,length(n))

x3(n>=2 & n<=22)=exp(j*(0.5)).^n

but i got the error in the definition, what can be the solution?

Try

n=-25:25;
x3=zeros(1,length(n));
x3(n>=2 & n<=22)=exp(j*(0.5)).^(2:22);
