That depends on what psi is, but with a nested loop this is trivial. What did you try?

n=10;
psi=rand(1,n-2);
chi = 0;
for k=1:n-2
i = nchoosek(1:n-2,k);
j = 1:k;
l = k+1-j;
il = i(:,l);
chi = chi+sum(prod(psi(il),2));
end
chi
% Or remove some of the unecessary indexing with j and l
chi = 0;
for k=1:n-2
chi = chi+sum(prod(psi(nchoosek(1:n-2,k)),2));
end
chi

@Aynur Resulzade You must kidding me. I'll delete my answer
