Convert that into a 1x3 vector using the reshape function. (The squeeze function would help as well.) Packaging it all into one line, we get this... double(M1) - double(M2) Now, how would you form the square of each difference? http://themedemo.net/mean-square/normalized-mean-square-error-matlab.html

You can create a standard network that uses mse with feedforwardnet or cascadeforwardnet. Valid values are: -) sd : standard deviation of observations (default). -) maxmin: difference between the maximum and minimum observed values ... Mean square error is 1/N(square error). ExamplesHere a two-layer feedforward network is created and trained to predict median house prices using the mse performance function and a regularization value of 0.01, which is the default performance function

If x and/or xref are cell arrays, then fit is an array containing the goodness of fit values for each test data and reference pair. If X is a matrix of shape NxMxP, sum(X,2) forms a sum over the columns of X, i.e., the SECOND dimension of X, producing a result that has shape Nx1xP. –user85109 Acknowledgments Trademarks Patents Terms of Use United States Patents Trademarks Privacy Policy Preventing Piracy © 1994-2016 The MathWorks, Inc.
