Next, to include depth weighting, we modified the source covariance matrix:  \begin{verbatim}  %% Depth-Weighted MNE  W_i = diag(sqrt(sum(L,1).^2./306));  lambda = trace(L*W_i*L')/(trace(Cn)*snr^2);  ev = eigs(L*W_i*L'+lambda*Cn, rank(data1)); 
...
Finally, we constructed a beamformer operator for the data:  \begin{verbatim}  %% Beamformer  N = 306;  M = 5124;  ev = eigs(Cd, rank(data1));
