Perhaps you are trying to pass a color image to surf, which does not work. Note that if you load a grayscale image, it will still be represented as RBG. Therefore you will have to first convert the image to grayscale.
A=imread('fig1.jpg');
B = rgb2gray( A );
surf(B,'edgecolor','none')
%optional
colormap(gray)
Note that x- and y-axis are pixel positions, as no dimensions were provided.
