vector.mat

I have a program that cuts out points from a two-dimensional vector that are at a distance 'd' from each other. The program starts working from the first element of the second column of the array. I want to add the value 'x0' to the value of this element and that the program starts with this value.

I have attached the vector to the message.

Thank you in advance.

This is my code:

format longG
d = 0.4053/sqrt(3); %0.4053
ii = 2;
a_0 = 0;
%a_0 = optimvar('a_0',43521); %!!!!!!!!!!!!!!!
general_t_d(:,1) = gn_nach(:,1);
Unrecognized function or variable 'gn_nach'.
general_t_d(:,2) = gn_nach(:,2);
general_t_d(:,2) = general_t_d(:,2) + a_0; % addition a_0
while ii < size(general_t_d,1)
    if abs(general_t_d(ii+1,2) - general_t_d(ii,2)) < d
        general_t_d(ii+1,:) = [];
    else
        ii = ii + 1;
    end
end

I will try to explain with an example:

we start from B1, if mod(B1 - B2) < 0.22 we delete A2B2 and continue to compare B1 with B(i), if B1 - B(i) >= 0.22 we leave this element (A(i)B(i)) fixed on it and similarly move down the table.

I attached the table to the comment.

this is how my code works now. I want this 'cutting' to work not from the beginning B(1) but from an element whose value is B(1)+0.00015, and all previous elements A(i)B(i) to be deleted. And that's all. Thank you in advance!
