a=imread('D:\canal images\df.jpg'); imshow(a); title('Original');
img=rgb2gray(a); imshow(img); title('Grayscale');
b=edge(img,'canny',0.40); figure,imshow(b); title('canny');

This error occurs, if the parent folder of edge.m is the current folder. Try this:
cd(tempdir)
and run the code again. Does it help? If so, remember that it can have strange side-effects, if one of the toolbox folders is the current directory.
