Deepak - it looks like you have copied this code from (perhap) https://www.mathworks.com/matlabcentral/answers/435101-this-is-my-code-and-i-trained-two-types-of-classes-in-there-a-building-as-class-1-and-a-mountain-as so you will need to make sure that you have the function FeatureStatistical in your MATLAB search path. And you will want to make sure that the function call is spelled correctly. Try changing

F=Featurestatical(im);

to

F=FeatureStatistical(im);
