Creating a loop to find next point in array

function [next_point, distance] = find_next_point(current_point, points_to_check, x, y)

distance = compute_distance(current_point, points_to_check, x, y) %find all distances in array

[distance, idx] = min(distance) %find smallest of these distances

next_point = points_to_check(idx)

end

If current_point = [1] and points_to_check = [2 3 4 5 6 7 8 9 10 11 12] how can I turn this code into a for loop so that it determines the smallest distance to the next point (taken from points_to_check) for each iteration?

e.g. after the first iteration current_point = [4] and points_to check = [2 3 5 6 7 8 9 10 11 12] so each iteration the current point is removed from points_to_check and the current_point changes depending on which is the closest point.

Edit: I just realized I misread what you wanted. I thought you needed to remove the distance, not current_point.

Assuming index for distance is same as index for points_to_check. Let me know if this works.

function [next_point, distance] = find_next_point(current_point, points_to_check, x, y)
next_point = [];
for i = length(points_to_check):-1:1

distance = compute_distance(current_point, points_to_check, x, y); %find all distances in array
[~, idx] = min(distance); %find smallest of these distances

%save array of answers
next_point = [next_point points_to_check(idx)];
%Update parameters for next run
current_point = points_to_check(idx);
points_to_check(idx) = [];
end
end

That works perfectly! Thanks for the help
