I don't know what to do with that alphabet soup of uncommented code. Read this and then fix your post: http://www.mathworks.com/matlabcentral/answers/6200-tutorial-how-to-ask-a-question-on-answers-and-get-a-fast-answer

'sir carefully look at the last 4th and the last 15th line..i have made them under star too..that particular syntax gives error.
i wanna save the image obtained in b to some array g(n),bt it gives error'
