Hi all,
i've checkek my script(using below code)for orders higher than 6,but faced with error as u can see.what should  i do to be able to solve this problem and evaluate the equation for degrees up tp 9??
ERROR:
??? Error using ==> times
Matrix dimensions must agree.
Error in ==> fit2dPolySVD at 70
coeffs = v*qqs'*u'*zs; 
Error in ==> svdfithc at 21
coeffs = fit2dPolySVD(X(:), Y(:), Z(:), order);
