function for bit rotation
显示 更早的评论
anybody help me to explain following bit rotation function :
function[data,nBits]=bit_rotate(data,nBits)
dataBits=log2(double(intmax(class(data)))+1);
nBits=rem(nBits,dataBits);
if nBits==0
return
end
shiftedData=bitshift(data,nBits);
lostData=bitxor(data,bitshift(shiftedData,-nBits));
rotatedData=bitshift(lostData,nBits-sign(nBits)*dataBits);
data=shiftedData + rotatedData;
end
