I have a vector [ 0 0 1 0 1 0 1] is there a quick way to convert it to a single number: 10101 ?

Does "quick" means fast or easy?
x = [0 0 1 0 1 0 1];
p = flipud([1; cumprod(repmat(10, size(x, 2) - 1, 1))]);
y = x * p;
This is fast, but it may look complicated on the first sight.

yes this would work, but it is not fast enough for my need. Thanks a lot though!

b =[ 0 0 1 0 1 0 1];
k = bin2dec(char(b+'0')) ;
dec2bin(k)
