How to perform the delete-d jackknife in matlab?

Hi, Can anyone advice me on how o extend the delete-d jackknife code sample. This sample code i have done in delete-1 jackknife:

X1 = [1,2,3,4,5];
X2 = [1,2,3,4,5];

for i = 1 : n
    if i ==1
        fprintf('i : %d \n', i);
        disp(X(i+1:n,:))
        disp('-----------')
    elseif i == n
        fprintf('i : %d \n', i);
        disp(X(1:(n-1),:))
        disp('-----------')
    else
        fprintf('i : %d \n', i);
        disp(X([(1:i-1),(i+1):n],:))  %(1:i-1) || (i+1:n); 
        disp('-----------')
    end

end

I would like to enhance to delete-d jackknife. I will appreciate if anyone can advice me to enhance without using he existing package in matlab because i will combine with my current model.

Thank you
