Hi all, When using corrcoef on a matrix. Is there a way to get the mean of all the values on the bottom left triangular side or the top right triangle?
All the best,

I am not sure exactly what you want ...
EDIT but not really different
N = 10;
x = randn(N);
y = corrcoef(x);
z = mean(y(tril(true(N))))

No thats not what I want, when doing corrcoef on a matrix I want the mean of the bottom left values.
I edited it to add the corrcoeft part and do the bottom-left and not top-right, but it doesn't change what I am doing. This what you want?
If you don't want to average the main diagonl, which is necessarily all 1's, then use Daniel's code with
z = mean(y(tril(true(N),-1)))

请先登录,再进行评论。
