Ran in:
picture=imread('flamingos.jpg');
g=rgb2gray(picture);
subplot(3,3,1),imshow(g),title('original');
pic = edge(g,'sobel');
subplot(3,3,2),imshow(pic),title('sobel');
... What this tells us is that you accidentally named the file of your code edge.m and so you conflicted with using MATLAB's edge() function.

Inside a file named edge.m you asked MATLAB to call edge(g,'sobel') . How is MATLAB to know that that call to edge() was to be a call to the MATLAB edge(), and not an attempt to call your current file edge.m recursively ?
