This might help.

% Creating random data for example
sig1 = rand(1, 2048);
sig2 = rand(1, 2048);
% Calculate correlation coefficient matrix between sig1 and sig2
R = corrcoef(sig1, sig2);
% Extract correlation coefficient value
corrcoefVal = R(1, 2);
disp(['Correlation coefficient between sig1 and sig2: ', num2str(corrcoefVal)])
