On this line:

y1=[N0 N0/2 N0/4 N0/8 N0/16 N0/32 N0/64 N0/128 ...N0/256 N0/512 N0/1024 ];

you use three dots to tell MATLAB that you will continue the code on the next line. But you don't.

Solution: get rid of the three dots. Even better (assuming that N0 is scalar):

y1 = N0 ./ pow2(0:10)

?huh? I don't see that at all. Did @Putra destroy the original post?
