This is what appears when the code is applied
Error using imread>get_full_filename
File "[name of input image file].[file format]" does not exist.
Error in imread (line 371)
fullname = get_full_filename(filename);

Ran in:
Try this:
grayImage = imread('coins.png');
subplot(1, 2, 1);
imshow(grayImage, [])
%impixelinfo
title('Original Image')
edgeImage = imgradient(grayImage, 'sobel');
subplot(1, 2, 2);
imshow(edgeImage, [])
%impixelinfo
title('Sobel Image')

You actually have to supply a filename to imread(). That's just a placeholder in the code.
% for example
A = imread('peppers.png');
