I'm having trouble understanding how to go about this problem. I guess I'm really not sure how to multiply out the arrays.

If anyone knows the problem I am referencing to, please help.

a = sqrt(2.8);
%%
x = 1:0.5:5
%%
n = 100
%%
sN = 1 - (x.*x)/(n^2-a*a)
%%
SN = prod(sN)
%%
s_infinity = a*sin(pi*sqrt(a*a + x.*x))./(sin(pi)*sqrt(a*a + x.*x))
%%
eN = 100*(SN - s_infinity)./s_infinity
