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.
