a = top_right(N,n)
[j , k] = size(N);
a = N([1:1:j-(j-n) , 1:1:k-(k-n)],1:n);
end

For "top right corner," the column indexing should not start at 1. E.g.,
a = N(1:n,end-n+1:end); % <-- Back off from end instead of starting from 1
But you might want to add code to cover the cases where the dimensions of N are smaller than n.
