How to return a specific index of a vector?

The problem I have here is that I want to return the index of the next point. If I input find_next_point(1, [6 7 8 9], x, y) the code returns everything I want except it displays that the next point is point 1 rather than 6 (which is the next point). I understand that this is just displaying the index from the vector [6 7 8 9] and returning that it is the first number in the vector, but how can I make it display the actual number instead e.g. 6 Hope this makes sense

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

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

end

current_point(next_point)

Can this be placed into the function somewhere?

function [next_point, smallest_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

[smallest_distance, idx] = min(distance) %find smallest of these distances
next_point = current_point(idx);

end

Thank you, it's working. I had to change it to:

next_point = points_to_check(idx)

since the input current_point was an array of 1 element and I was getting an error of index exceeds the number of array elements.

Really appreciate your time and help!

Oh, right, that makes sense.
