Error : Attempt to execute SCRIPT edge as a function

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.

ok thank you ...

but why it dont show me the edge plot?

[Walter Roberson]

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 ?
