Write a function which calculates the average intensity level of an image. From the command line use this function on the image doge.jpg and show the resulting average.

I have been trying something like this, but i'm just so bad. the image is already on grayscale

NMD 100 i function average (a) 2 a = imread('doge.jpg'); 3 n = sum(a); 4 m = lenght (a); 5 5 mean = n/m; 6 disp('The avarage of the image is:') 7 disp (mean) 8 8 end 9
