I am using Matlab 2012 and got this type of error.. Thanks for your reply...

Error using randi First input must be a positive scalar integer value IMAX, or two integer values [IMIN IMAX] with IMIN less than or equal to IMAX.

Error in One_image (line 11) idx=randi(n);

This is because your folder is empty, I mean it doesn't contain jpg files
