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 have submitted a single example sir actually it is about imshow(mag(i,j),256) it is a line in walsh transform program in image processing but sir i got my answer by typing imshow(mag(i,j)) only thank you so much sir

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