im1=imread('stallite1.JPG'); figure subplot(1,3,1),imshow(im1),title('original image') ref=rgb2gray(im1); subplot(1,3,2),imshow(ref),title('gray image')
N = imnoise(ref,'salt & pepper', 0.02); subplot(1,3,3),imshow(N),title('noise image') error = immse(N, ref); fprintf('\n The mean-squared error is %0.4f\n', error)

immse was introduced in version R2014b and requires the image processing toolbox. If you're on an earlier version or don't have the image processing toolbox, you'll get the error you see.
Since imnoise does not error we can conclude that you're using a version before R2014b.

You have the image processing toolbox installed already since imnoise works.
If you do need that function, then your only options are to upgrade matlab to at least R2014b or write the code for the function yourself.

If you're on a software maintenance service then the upgrade (to any version) is free. Otherwise, yes you will have to pay. You're better off contacting mathworks directly with your license number. They'll be able to tell you directly if it's free and if not, how much.
