- iterate over the vector backwards.
- build a logical mask within the loop, and after the loop use the mask to remove all relevant elements at once.
In the following code if the condition is met i want to remove those two respective elements from the array 'New'. But i get an error saying 'Index exceeds matrix dimensions'.

New = [800,750,740,700,500,300];
radius=50;
for k=1:111
for i=1:length(New)
for j= (i+1):length(New)
d(i,j)= sqrt((a(k)-New(:,i)).^2+(b(k)-New(:,j)).^2); % 'a' and 'b' are two matrices of size 1*111
if (d(i,j)<=radius)
New(i) = [];
New(j) = [];
end
end
end
end

This is a common beginner mistake. If you remove the first element of a four element vector, then it resizes to have three elements. But if your code still thinks the vector has four elements and you try to access the fourth element, then you will get an error. That is basically what you are doing.
