There is nothing wrong with the code you have quoted from the MATLAB documentation:
J = checkerboard(20);
figure
imshow(J)
That should work as long you have the Image Processing Toolbox installed. (The Image Processing Toolbox contains the checkerboard function.)
The problem is occuring in your next line:
Fringe Chessboard
What is Fringe supposed to be? Is that your function, or a function that somebody gave you? It is not a function in MATLAB or any other MathWorks product.
