Below is my code for arbitrage analysis on DIA and the DOW

I need the x and the i to output to seperate vectors.

If someone can please help me I cant find how to do this anywhere.

clear
clc

load DIADOW.m

DIA = DIADOW(:,1);
DOW = DIADOW(:,2);

N = length(DIA);
tol = 20;
for i = 1:N
    if abs(DIA(i)*100-DOW(i))> tol
        x = DIA(i)*100 - DOW(i)
        time = i;
    end    
    
end
