how do I store an array of functions?

I want to store the following function for i=0:170
f = @(u) 2/(pi*sqrt(1-((sin(i/2)^2)*(sin(u)^2))));
and evaluate using my function.

What is the point in creating 171 copies of (almost) the same function, when you can just create one?:
f = @(u,i) 2/(pi*sqrt(1-((sin(i/2)^2)*(sin(u)^2))));

An error message tells me
Nonscalar arrays of function handles are not allowed; use cell arrays instead.
Is this what are looking for?
>> f{1}(pi/2)
ans =
0.63662
>> f{100}(pi/2)
ans =
0.88291
>>
where f is created by
%%
f = cell( 1, 171 );
for ii = 0 : 170
f{ii+1} = @(u) 2/(pi*sqrt(1-((sin(ii/2)^2)*(sin(u)^2))));
end
Or why not
%%
f3 = @(u,jj) 2./(pi*sqrt(1-((sin(jj/2).^2).*(sin(u).^2))));
f3(pi/2,0)

i = 0:170 ;
f = @(u) 2./(pi*sqrt(1-((sin(i/2).^2).*(sin(u).^2))));
f = f(i) ;
plot(i,f)
