Is this any different than your prior post http://www.mathworks.com/matlabcentral/answers/116422-how-to-perform-cancatenation-of-binary-numbers-using-matlab?

Here is one way, if the input is a character string:
char(num2str(x'=='0'))'
I feel that there must be a better way, and I am just being dumb.

char('a'-x);
where x is your input string.

'a' is the character string for the letter 'a'. This is a nice trick to "subtract" your string x from the ASCII character 'a', which gives you what you want.
So, if
x = '0110';
y = char('a'-x);
will result in y having the value '1001'.
