MSE = reshape(mean(mean((double(M1) - double(M2)).^2,2),1),[1,3]); If this seems complex to you, then you are best off splitting it into several lines, with comments that remind you what you did for later. Predicted = [1 3 1 4]; % One way is to use the Root Mean Square function and pass in the "error" part.
