How do I find the correlation coefficient between two vector arrays?

Hi guys, I transformed 2 matrices into vector arrays, so like each vector has 1 column and 2850 rows. How do I find the correlation coefficient between the two vector arrays?

I tried to use corrcoef, but I don't think it works in this case yes?

Thank you!

R = corrcoef(A,B)

Please read about corrcoef.

are you sure this works for vectors? My results gathered from it is always 1 or 0.99 which is really rare

I also have the same question, I have two column vectors, When I use corrcoef it gives me 1 but when I use xcov it give me a logical answer, which one is correct?

What does this figure look like?

scatter(A,B);
