Hello every body,
I have found the covariance of one subject like the cod ebelow:
%% Covariance
cov_EC1 = cov(subs_P01EC1_alpha(:,:));
cov_EC1 = abs(cov_EC1 - diag(diag(cov_EC1)));
figure;
imagesc(cov_EC1);
axis square;
cb = colorbar;
cb.Label.String = 'Covariance level';
title('|Covariance, P01,EC1Active|')
ylabel('nodes');
xlabel('nodes')
Now, I want to find Covariance of 14 subjects in a matrix. How should I code this?
Thank you in advance for your help.

I want to have a average matrix of 14 subjects, how can I generalize it for 14 subjects?

That is just rephrasing your original post. Do you expect me to rephrase my comment as well?
