How to append ones or zeros

I have array of 527 and 532 bits. I want to do some processing on bits but for that processing it is mandatory that array have elements in the multiple of 530 or 535. How can i append those necessary bits in MATLAB code.

A = rand(527,1) ;
N = 530 ; % 535
iwant = [A ; zeros(N-length(A),1)] ;
