I have a code that calculates the Euclidean distance between X and Y and selects the minimum coordinate, and once that minimum coordinate is calculated, it removes it from the loop. My problem is that after the first step, what happens if the coordinate that's removed is not successive but before the first point? Basically I want to re-write this code so that it relies only on the coordinate of interest and not the index. I don't want to store the index anymore. Any help will be appreciate. Thank you
X = Observed_Signal_Positive_Inflection_Points_Coordinates;
Y = Positive_Inflection_Points_Coordinates_denoised;
X
Edited_Array = Y; % this will take care of the changing array size
nX = size(X,1);
Index = zeros(1, nX);
for k = 1:nX
ED = pdist2(X(k,:),Edited_Array,'euclidean');
ED = ED'
[Minimial_Euclidean_Distance, Index(k)] = min(ED(:,1), [], 1);
Minimial_Euclidean_Distance
Index(k) = Index(k) + (k-1)
Minimal_Positive_INFLP_ED(k,:)= [X(k,:), Y(Index(k),:), min(ED(:,1))];
Edited_Array(Index(k)-(k-1),:) = [];
end

First of all, avoid don't close the lines. Usually you don't want to print the results of each line, so use ";" at the end of each line and print your results after the loop.
