How to find Covariance matrix of 14 subjects

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.

You already have code to calculate the covariance for an arbitrary list. What is your question? Why can't you repeat the code you already have?

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?
