I found one on matlab central which is probably what you want http://www.mathworks.com/matlabcentral/fileexchange/21383-rmse "calculates root mean square error from data vector or matrix and the corresponding estimates." --Nasser Subject: calculate root Forgot your Username / Password? For matrices, Y contains the RMS levels computed along the specified dimension DIM. Root Mean Square Error Example squareError = err.^2; % Then take the "mean" of the "square-error".

For example, if X is an N-by-M matrix with N>1, Y is a 1-by-M row vector containing the RMS levels of the columns of X.`Y`` = rms(X,DIM)` computes the Learn more MATLAB and Simulink resources for Arduino, LEGO, and Raspberry Pi test Learn more Discover what MATLAB ® can do for your career. Best regards, Wolfgang Comment only 10 Oct 2008 Felix Hebeler @Gary: no, you need two sums if you process matrices, the first sums across all columns, the second then sums across see this here United States Patents Trademarks Privacy Policy Preventing Piracy Terms of Use © 1994-2016 The MathWorks, Inc.
