winscaled = round(w.*(2^(B-2)/max(w)));

filename = 'window_coeff.coe';

fid = fopen(filename,'wt');

fprintf(fid,'memory_initialization_radix=16;\n');

fprintf(fid,'memory_initialization_vector=\n');

for i=1:N

What error does it show?

Did you happen to store your script in a file hamming.m ? If so then that would lead to a problem.

If the error is about it not knowing a function named hamming, the possibly you do not have the Signal Processing toolbox installed or licensed?
