Convert vector to single double number

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

Answer 1

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.

b =[ 0 0 1 0 1 0 1];
k = sprintf('%1d',b) 
iwant=str2double(k) ;

[Terek Li]

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)
