imshow(mag(1,1),256) this is the line which is executed and the error returned is
Error using imshow>preParseInputs (line 456) The syntax IMSHOW(I,N) has been removed. Error in imshow (line 214) varargin_translated = preParseInputs(varargin{:}); pls suggest me with a solution sir and i am using matlab 2014a

It's not possible to be sure what you want to do. However, trying to display a single pixel mag(1,1) doesn't usually make sense. If mag is your image, perhaps you mean
imshow(mag);
or
imshow(mag, []);
or
imshow(mag, [0 255]);
The correct syntax for imshow is shown in the documentation. Referring to that is the best way to find the answer.

I guess i and j must be vectors then. If they are scalars, mag(i,j) is a single pixel.
