found many option, but I am stumble about something,there is the formula to create the RMSE: http://en.wikipedia.org/wiki/Root_mean_square_deviationDates - a VectorScores - a Vectoris this formula is the same as RMSE=sqrt(sum(Dates-Scores).^2)./Datesor did asked 6 years ago viewed 53294 times active 2 years ago Get the weekly newsletter! set(gcf, 'units','normalized','outerposition',[0 0 1 1]); Maria Maria (view profile) 18 questions 2 answers 0 accepted answers Reputation: 2 on 21 Apr 2014 Direct link to this comment: https://www.mathworks.com/matlabcentral/answers/126373#comment_209202 Dear Mr Image Phil Chan 19.218 προβολές 7:51 How to calculate RMSE through Matlab - Διάρκεια: 4:46. http://threadspodcast.com/mean-square/mean-square-error-of-two-images-matlab.html

Use the .^ operator. (double(M1) - double(M2)).^2 Next, mean squared error implies that we take the mean over all rows and columns. It really sounds like homework since real world problems are usually not as easy as this.
