% Assuming X is your matrix
X = ...; % Your matrix here
% Compute the element-wise product of X and its conjugate
productMatrix = X .* conj(X);
% Find the linear index of the maximum value in the product matrix
[~, linearIndex] = max(productMatrix(:));
% Convert the linear index to row and column indices
[l, k] = ind2sub(size(X), linearIndex);
