i used wiki's example to check for its correctness: http://en.wikipedia.org/wiki/Cyclic_redundancy_check#Computation_of_CRC
msg = [1 1 0 1 0 0 1 1 1 0 1 1 0 0]; poly = [1 0 1 1]; the program gives r = 1 0 0
i've also tried to do the XORs by hand... i found it is indeed 1 0 1, not sure where goes wrong
