hi everyone I want to find the correlation between these two binary strings x and y
x=[1111111111111111111111111111111111111111111111111111111111111111];
y=[1000000001011001010110111110010101011010010000100010111101111110];
using the formula attached as figure. the value of E is 0.05 or 50%.
Thank you in advance

If the values are represented by 0 and 1, then it seems to me using 0.5 would make more sense...

R = sum((x - E).*(y - E)) ./ (sqrt(sum((x-E).^2)) .* sqrt(sum((y-E).^2)));

It handles all of x and all of y, assuming that they are the same size. It uses vector operations so it does not need to loop. The sigma operation in the equation is sum() here.
