'1101111000111101'-48
sprintf('%d',[1 1 0 1 1 1 1 0 0 0 1 1 1 1 0 1])

Another option to get back a string is to simply revert the previous operation:
v = [1 1 0 1 1 1 1 0 0 0 1 1 1 1 0 1];
char(v + '0')

More generic for the numeric conversion is
sscanf('1101111000111101','%1d')
as can set the field width; the subtraction "trick" works for single digits, correct; however, I'd write
'1101111000111101'-48
as
'1101111000111101'-'0'
instead to remove the "magic number" 48 from the expression just as a stylistic change.
